The Argentina international’s two-year loan deal at Old Trafford will be at its end in the summer and Tevez is yet to sign a permanent contract.
“The Tevez thing, it is a media story,” the United boss told L’Equipe Magazine.
“As he is not our player, everything that goes on with him is analysed on this premise.
“It’s good for papers to say Tevez isn’t playing. But when it is (Michael) Carrick, (Darren) Fletcher, (Ryan) Giggs or (Paul) Scholes, nobody could care less.
“I have 23 players. Up front, I must choose between Tevez, (Wayne) Rooney, (Cristiano) Ronaldo, (Dimitar) Berbatov, Nani, Park Ji-sung, Giggs, Scholes and some youngsters.
“You can’t play them all together.
“Players like Tevez, Rooney and Ronaldo are still progressing. For me, a player reaches maturity at 26-27.”
