Barcelona has their way same as Bayern. Barcelona's progressive possession style of football under Xavi can kill any team playing against them. we have seen football destroy the best teams in years. But it can also be worked against. now that's not just the problem. Barcelona plays the way they play and when it seems not to work for them they end up being bleeped.
There was a slight mistake that Xavi made, namely with a long passing strategy, it was seen when Gavi was playing with an automatic long ball that happened. If from the beginning Xavi used more of a tiki-taka press, the style of play and rhythm would be much different and the possibility of winning could happen. Here Xavi lost the game of tiki-taka because what he used was a long ball.
