Pep's explained the amount of crosses; it is deliberate. The quality of the balls in would not always be what he was looking for but it's done because Saints were fairly narrow and deep, filling their box with players. That makes it very hard to play through and of course hard for our players to get on the end of crosses but the space is there to cross. However, what Pep is very much looking for is the second ball, where the opponent stops the cross but doesn't clear it properly, particularly where the ball is fizzed in and then bounces about and the defenders lose their orientation. Basically, it's a case of playing the odds i.e. eventually the ball will break kindly for us (e.g. Walker's goal) or the cross actually finds it's mark (Sergio's goal).
