The Frenchman completed his move to the Spanish giants from Portsmouth earlier this month.
Diarra told Le 10 Sport: “It’s up to the club to make a decision; they will announce it within a couple of weeks. They already have an idea of what they are going to do.
“I will accept the club’s decision. Anyway I signed for fix years, not for six months. But of course I want to play Champions League football and I’m going to do everything to be there against Liverpool.”
