1) Barcelona - They are awsome at passing the ball and keeping calm while under pressure, they never panic and their moves are so slick! Their flicks and tricks are not for show, they are part of Barca's style and boy is it affective!
2) Villareal - Ok, this is based on their last season displays and when they played Arsenal in the 2nd leg of the Champions League they never gave the ball away, they shifted it about quickly and in style. Other games they were also impressive but mainly in CL
3) Arsenal - A few years back they would of been top of the list as they use to attack in numbers within seconds, pass, run, pass, run, pass, finish into empty net. They can't play that style aswell now but with Fabregas & Henry the side still plays beautiful football when they are on fire.
99) Chelsea - They spent soo much money and have players like Robben, J.Cole, Shevchenko, Ballack & Drogba who all play beautiful football but why can't they play beautiful football as a team? Only Mourinho will know that one.
