The Mali international is recovering from major injury suffered last season, but is adamant he wants to be part of new president Florentino Perez's plans.
Diarra said: "No-one from the club has told me they won't be counting on me next season. In any case, I still have a contract with Real.
"When preseason begins, I will be able to join my teammates.
"It will be sensational to play for Real Madrid if the president can bring in these players that everyone is talking about."
