Welcome to The Blueprint. A weekly series where myself (pauciloquxnt) and FUTWIZ will be venturing into the world of real life tactics and how we can recreate them in FC 25. This week we’ll be looking at José Mourinho‘s UCL-winning FC Porto of 03/04, hope you enjoy it!
How Mourinho’s 2003/04 Porto Conquered Europe with Tactical Discipline and Deco’s Brilliance
The 2003/04 season was a defining moment in José Mourinho’s career, as he guided FC Porto to a historic treble: the Primeira Liga title, the Taça de Portugal, and most famously, the UEFA Champions League. Mourinho’s tactical intelligence, built on defensive discipline, quick transitions, and attacking efficiency, allowed Porto to outmanoeuvre superior opponents and claim European glory.
Tactical Framework
Formation and Build-Up Play
Mourinho’s Porto operated in a 4-4-2 diamond, allowing for defensive solidity and vertical progression. The backline featured Ricardo Carvalho and Jorge Costa as the centre-back pairing, complemented by Paulo Ferreira and Nuno Valente as full-backs. While the full-backs provided width, their priority was defensive stability rather than relentless attacking runs.
In midfield, Costinha sat as the single pivot, shielding the defence and breaking up opposition play. Ahead of him, Maniche and Pedro Mendes played as dynamic box-to-box midfielders, offering both defensive support and attacking penetration. The key orchestrator was Deco, the advanced playmaker, who dictated tempo, played between the lines, and supplied the strikers.
Vítor Baía’s role as goalkeeper was functional rather than revolutionary—he was reliable in goal, commanded his box well, and distributed conservatively, mostly playing short to the centre-backs or Costinha to maintain control in build-up.
The strike duo of Benni McCarthy and Derlei combined technical ability, movement, and lethal finishing, allowing Porto to exploit defensive weaknesses with fast, direct attacks.
Porto’s build-up play was patient but purposeful. The centre-backs and Costinha ensured composure, while full-backs provided width. Deco frequently dropped deeper to act as the main progression link, while Maniche and Mendes would make late runs into space. Their build-up wasn’t about sterile possession—it was about creating advantageous positions quickly and ensuring defensive coverage when possession was lost.
Deco: The Tactical Engine
At the heart of Porto’s success was Deco, the side’s most technically gifted and tactically versatile player. Operating as a free-roaming playmaker in the number 10 role, Deco was Mourinho’s primary creative outlet and the player who dictated the game’s tempo.
His role had three main functions:
- Dictating Tempo & Playmaking – Unlike traditional number 10s who focused solely on final passes, Deco was deeply involved in build-up, frequently dropping into midfield to help circulate possession and evade pressure. He averaged 69.4 touches per game in the Champions League, the highest in the team, and maintained an 86.2% pass completion rate, despite often operating in high-pressure zones.
- Defensive Contribution – Mourinho’s system demanded hard work from all players, and Deco was no exception. He covered space intelligently, pressing in advanced areas but also tracking back when needed. He won 5.8 duels per game, with a 64% success rate in tackles, showing his balance between creativity and industry.
- Final Third Influence & Direct Goal Threat – Deco’s vision allowed him to supply defence-splitting passes to McCarthy and Derlei, while his own goal threat was considerable. He recorded 4 goals and 5 assists in the Champions League, with 2.4 key passes per game, making him Porto’s most decisive playmaker. His performance in the final against AS Monaco, where he assisted one goal and dictated play, solidified his reputation as the tournament’s standout midfielder.
Mourinho built his system around Deco’s intelligence, movement, and technical brilliance, allowing Porto to attack efficiently while maintaining midfield balance.
Attacking Play and Goal Threat
Despite their pragmatic and compact setup, Porto was far from defensive-minded. Mourinho’s team was lethal in transition, often bypassing midfield with direct vertical passes to quickly reach attacking areas. Their attacking play was built on:
- Quick combinations between Deco and the strikers.
- Overlapping full-backs in selective moments to stretch defences.
- Maniche’s late runs into the box, offering a secondary goal threat.
- Set-piece efficiency, with Carvalho and Costa dominant aerially.
Porto scored 63 goals in 34 league games (1.85 per game) and scored 20 goals in 13 Champions League matches, proving their efficiency against high-level opposition.
In Europe, Deco contributed 4 goals and 5 assists, McCarthy scored 4 crucial goals, and Derlei added 3 goals and 2 assists, showing their multi-faceted attack. Porto was never a high-possession team, averaging around 50-55% possession domestically but often dropping lower against stronger opposition in the Champions League to exploit counter-attacks.
Defensive Organisation and Pressing
Mourinho’s defensive system was rigid, disciplined, and structured. His team maintained a mid-block with a well-drilled zonal marking system. They pressed selectively, often allowing opposition centre-backs to have the ball before triggering a press when it reached midfield.
- Porto conceded just 19 goals in 34 league games (0.55 per game)—the best record in Portugal.
- In the Champions League, they conceded only 8 goals in 13 matches, despite facing top teams like Manchester United, Lyon, and Deportivo La Coruña.
- Porto recorded 15 clean sheets in 34 league games and 7 in the Champions League, showcasing their defensive resilience.
- Ricardo Carvalho led the team with 4.7 interceptions per game, while Costinha made 2.8 tackles per game to break up play.
Their defensive line was not excessively high, ensuring they weren’t exposed to pace in behind. Instead, the midfield block was compact, with Costinha and the centre-backs acting as the defensive spine, while Maniche and Mendes applied pressure further up.
Statistical Insights and Achievements
Porto’s season was one of dominance:
- Primeira Liga: Won the title with 82 points, finishing 8 points ahead of Benfica.
- Champions League: Defeated Monaco 3-0 in the final, showcasing Mourinho’s tactical perfection in big matches.
- Best Defence in Portugal: Only 19 goals conceded all season.
- Deco’s 9 goal contributions (4G, 5A) in the Champions League, showing his key role.
- Maniche & Deco combined for 30+ goal contributions, highlighting midfield influence.

The Tactics
Build-Up Style is set to Counter, so that we can break quickly and transition with directness.
Line Height is set to 50 so that we can maintain that mid-block out of possession. Your press must be selective in order to maintain your strong defensive structure.
We put the GK on Sweeper Keeper with a Balanced focus so that they sweep up any loose balls over the top. Nothing crazy here, but this is essential to support the defenders.
Our CBs are on Defender with a Defend focus. This will mean they are there for defence only, but do look at one being more of a mobile defender who can pass to recreate Carvalho’s role.
The LB and RB will be on Fullback with a Balanced focus so that defence remains their priority. Mourinho played with a ‘one up, one down’ style, so this means we can trigger our runners with L1, to get them involved, but the opposite side will maintain their shape.
The CDM is on Holding with a Defend focus. This is so that they can screen the back four effectively, and not venture too far forward, always ensuring you have at least four players back at any one time.
Both CMs are on Box to Box with a Balanced focus. This is so they contribute in all phases of play. In order to recreate the roles of Maniche and Pedro Mendes, have a more attacking player on the left, and a more defensive player on the right of the two.
CAM will be on Playmaker with a Balanced focus. This is so that they drop slightly deeper to orchestrate attacks, but also be the main playmaker. We want everything to pass through them in our attacks.
Finally, the STs are on Advanced Forward with a Complete focus. This is so that they can make runs into the channels as well as be direct through the middle. We want them making runs at the opponent’s defence and this is the perfect role for that.
Tips and Tricks
- Track back manually with your CAM and CM’s before you make the switch to the CDM or defenders. This will ensure you keep your shape for as long as possible.
- Roles ++ are favoured because of transition speed with the Counter build up style.
- Do not drag your full backs too high to press, remember that the defensive shape is super important to your success..
- Your CAM is your orchestrator, they need to be very Deco-esque. Great at dribbling, can make those key slide-rule passes and also be able to quickly interchange with the STs. They also need to be able to finish a chance.
- Your STs should be mobile and quick, as they will be running into channels from time to time and trying to beat the last man off their shoulder.
Conclusion
Mourinho’s 2003/04 Porto side was a tactical masterclass in defensive structure, midfield control, and efficient attacking transitions. His combination of pressing triggers, compactness, and clinical finishing allowed Porto to conquer both domestic and European competitions.
Deco was the heartbeat of the team, providing creativity, work rate, and final-third magic, while the defensive core of Carvalho, Jorge Costa, and Costinha ensured stability.
Baía’s reliability in goal, Deco’s orchestration, Costinha’s defensive intelligence, and the fluid movement of McCarthy and Derlei formed the foundation of a team that remains one of the greatest underdog success stories in Champions League history. This success propelled Mourinho to Chelsea, where he refined his tactical ideas further, but his Porto team remains a perfect example of how a well-drilled, tactically astute side can defy the odds and conquer Europe.
