Zlatan Ibrahimovic and Lionel Messi have resumed full training with Barcelona ahead of Sunday's 'Clasico' against arch-rivals Real Madrid, the club said on Friday. "(Coach) Pep Guardiola was boosted by the return of the Swedish striker and Argentinean forward to the squad," Barcelona said on their official website. Ibrahimovic and Messi, who is a frontrunner to win the 2009 FIFA World Player of the Year award, recovered from hamstring and thigh injuries respectively. They were kept on the bench as Barca claimed an easy 2-0 Champions League victory over Inter Milan on Tuesday. However, it is not yet certain that they will start against Real at the Nou Camp on Sunday night. "There was no indication being given as to whether they would be given the green light to play against Madrid," Barcelona added. Real are on top of the Primera Liga table with 28 points, one ahead of defending champions Barcelona.
