Do we try Real Madrid tactics, try and get at them and attack? Or Chelsea tactics and defend for lives and score set piece winner?

Defend - focus on set pieces.

We pass them off the park, and beat them at their own game. :-)

(PS then I woke up)

I think we would beat them. We are a big game team these days.

Arsenal and Swansea passed us off the park, Barca would be much worse.

At home we can beat anyone and against Barca I'd like to think about 50% of the time we played them we wouldn't lose. At the Nou Camp we would struggle.

Bollox. We were in poor form in both of those defeats.

Mancini has taken the best aspects of Mouhrino's Chelsea side and Arsene's "invincibles" side and blended them together.

We have strength,power,commitment married to flair,style and creativity. We should take them on.

I think we would lose but then we dont posess a player that comes from another Planet.

But we might have signed Bale by then. Oh, by another planet you mean....

Use width of full-backs to beat their forward line and then just bully Busquets, fucking bully him. You beat their pressing, you beat Barca.
Edit: I managed to forget about Messi...don't single him out on the pitch, as in don't have 2 men trailing him, pick up man for man and cut off that '3 options' rule they have.
