Yes, people always tend to criticise their defense (Pique is awful though) but what can they do if Benzema, Isco and Ronaldo are running at them at full speed ? Their pressing isn't good enough to play the way they want to play.
The midfield Busquets-Xavi-Iniesta has declined so much in only two years. Busquets doesn't seem capable of protecting the back four, he's beaten in every 1v1 too now. Xavi can't control a game for shit now, he only pass it sideway and pressed he lose the ball quite often. Iniesta doesn't break opposition lines like he used too, no killer ball and offer nothing defensively. They need a complete overhaul.
Guardiola said in his book that his Barcelona never played better than against Chelsea in the first half of the semi 2012, so we eliminated the best team ever playing at their best with 10 men.
Thiago is 23 years old. At 23 years old, Cesc was a world (with a assist in the final) and european champion and played in a UCL final against his boyhood club. He also bossed Zidane and co at Bernabeu at 18.
He was very good playing with Alcacer but it's not a surpise, he plays very well in a system with two strikers, he was amazing when he played behind Falcao.
People are just never happy, when we attack like crazy, score goals and concede they want us to be more compact and that's exactly what happened yesterday and they are still not happy. You have to choose.
