What tactics should Manchester United use in the 2011 Champions League final?

In the Champions League final, Barcelona VS Manchester United, the coaches of two top European teams, but regardless of the score or the scene in Western Europe, Manchester United was basically completely defeated. Except for Manchester United's advantage in the opening 10 minutes, they were passively beaten the rest of the time. This is by no means a reflection of their true level, but a problem with Manchester United's tactical arrangements. Ferguson saw the remnants of Barcelona's defense, especially the two wingers who thought they had an opportunity and sent out a 4-3-3 formation. However, the two wingers did not get any advantage from the Barcelona full-backs. On the contrary, the midfielder changed due to the reduction of personnel. It is thin so that Xavi and Iniesta can calmly control the ball and organize in the midfield, thus completely giving up the initiative to Barcelona. In fact, Chelsea has pointed the way for Manchester United in the semi-finals. Hiddink arranged multiple thugs in the midfield as midfield engineers when he arranged his formation, exerting great pressure on the dual core of Barcelona and Messi, and narrowing the gap as much as possible. Their ball control space and contact lines meant that in the end Barcelona could only narrowly escape, and for a time even Guardiola was desperate. Any team that plays against Barcelona will not end well. Real Madrid in the league 2:6 and Bayern in the Champions League have proved this in both rounds. It may also be that Manchester United itself lacks defensive midfielders, so that this season’s Champions League encounters When it comes to Lyon, Barcelona are very passive, so Manchester United needs to introduce one or two engineer midfielders next season to deal with the technical teams in the Champions League!
