Pretty obvious Roura got the tactics all wrong yesterday. Barcelona have been lacking since Villanova went for treatment. To counter the parking the bus its obvious you play two wingers to stretch the pitch. Tello and Pedro. Iniesta as a left winger just drifted in the middle the whole time never outside. When Villanova left the stretching the field tactic was not being employed anymore. They made the pitch the narrowest it could be to make it as compact as possible. At the Nou camp this is not going to happen. USE THE DAMN WIDTH!
Also players didn't press for the ball it was a lazy effort from lots of them just walking. Puyol cannot be played in games where most the team is going to be so far up the pitch. Mascherano is perfect for those kind of games and has the pace to recover, he also distributes the ball better.
