Barcelona starting lineup (4-3-3): Victor Valdes; Adriano, Carles Puyol, Javier Mascherano, Dani Alves; Sergio Busquets, Xavi, Andres Iniesta; Cesc Fabregas, Lionel Messi, Alexis Sanchez.

*That Chelsea shape could also be a highly lopsided 4-4-1-1 or a 4-2-3-1 with Lampard and Mikel in the pivot and Meireles wide right. It's kind of hard to say. We'll see what happens when the match starts.
I'm not sure why Gerard Pique is on the bench for Barcelona, but that's a relatively weak back line for Drogba to hit. This should be an interesting one.
