Barcelona ace Xavi admits they're similar to Champions League opponents Arsenal.
The two team face off next week.
"Watching Arsenal is almost like watching Barca. Everything goes through Cesc and Nasri," Xavi told the Daily Mail.
"But the difference is that at Arsenal each player is a product of whatever youth system he came through. Here we have players who have been at the club for 10 or 12 years and that is the difference - everything comes automatically.
"Here they make you think from day one. The first thing you do when you join this club is rondo (the passing drill with one player trying to win the ball back and three or four players passing one-touch between themselves). It's think, think, think, and it teaches you the responsibility of keeping the ball and the shame of losing it.
"You lift your head before you receive the ball, you look to see if you are in space, and who else is in space, and you play the ball first time. Modern football is so quick that two touches means too slow."
