The injury report will be pretty key to the match.
Lots of key injuries for both sides.
Out for Arsenal: Alex Song, Robin Van Persie, Cesc Fabregas, Wlliam Gallas, Andrei Arshavin, Aaron Ramsey
Somewhat Questionable: Sol Campbell
Out for Barcelona: Zlatan Ibrahimovic, Gerard Pique, Carlos Puyol
Doubtful: Jeffren, Yaya Toure, Andres Iniesta
Thierry Henry is apparently still having calf problems as well.
For both sides the question is: who starts at central defense?
