From my perspective there's only one answer to how you play against them.
They close down and harass each player on the ball much more than peps Barca team, then when they get the ball back the players know exactly where to launch a first time ball to one of their rapid players, robinson and Arnold are both good players but the tactics make them look like world beaters. Quick crosses to the 6 yard box, they will be practicing that in training ever day, hence why they're so effective
The answer is to play like them, the Chelsea game under Dunc would have been a good example, don't give them a second on the ball.
I'm worried now that under Ancelotti, we will be like Spurs with Mourinho, the game has changed now and teams trying to play passing (boring) possession football will be punished. Rodgers with Leicester and Wilder with Sheffield have the right idea.
