Barcelona can cut Real Madrid's lead at the top of La Liga to a single point this weekend with a victory in Saturday's much-anticipated El Clasico at the Nou Camp.
Pep Guardiola's side were 11 points behind their bitter rivals earlier in the season, but 11 successive wins have put them right back in contention.
However, a first triumph at the Nou Camp for Jose Mourinho would open up a seven-point gap for his team with just four games remaining.
Alexis Sanchez could feature for the hosts, despite suffering from a minor knock, while Gerard Pique is expected to return in defence.
Madrid should have Marcelo at their disposal, with Xabi Alonso also coming back from a one-match domestic suspension.
