Sturridge will replace Didier Drogba and comes off an impressive two-match spell with England U21.
Ancelotti said: "Sturridge trained very well last year and he has improved a lot. I think it is the time for him to show us his quality. He has fantastic ability, he is quick with the ball and it is time for him to put his power on the pitch for us.
"He has different skills compared to Drogba. I have never seen a striker as quick as he is."
