The Chilean winger returns as the Spaniards make five changes following victory over Deportivo La Coruna, whilst Neil Lennon hands Scott Brown a start in midfield
Sergio Busquets, who is suspended after receiving a red card against Benfica last time out, is replaced by Marc Bartra, while Adriano, Xavi and Pedro also come in for Montoya, Fabregas and Tello respectively as Tito Vilanova makes five changes from the side which beat Deportivo La Coruna.
Celtic boss Neil Lennon, meanwhile, makes four changes to the side which comprehensively saw off St Mirren at the weekend, but is without James Forrest and Kris Commons, who have failed to shake off groin and hamstring injuries respectively.
The good news for the Bhoys, though, is that Scott Brown is able to take his place in the starting line-up after passing a late fitness test on a hip problem.
Mikael Lustig, Emilio Izaguirre and Georgios Samaras were all rested for the 5-0 thrashing at the weekend but have also been restored to the starting line-up, in what appears to be a defensive 4-5-1 setup.
