Its all down to Barca really, (In which I do think they will advance) Depends who is ready to show up and if they can change their tactics. If I were Milan, I would do exactly the same thing to exploit them. Force them to play wide, condense Xavi's space and have two men always next to Messi, forcing his right foot Lampard esq. Get ready on the counter and ALWAYS put pressure on Pique. Hopefully they can go through and hopefully Barca put Iniesta on the wing again.
