Defending Champions Barcelona host Arsenal tonight in the Champions League with both sides missing several key players. Arsenal will be without captain and top-scorer Cesc Fabregas after the Spaniard broke his leg in the reverse of this fixture in London, with William Gallas, Andrei Arshavin and Alex Song all missing out as well. Barcelona cannot call on either of their first-choice centre-backs, Andres Iniesta, or Zlatan Ibrahimovic, who scored both goals in the first leg.
