Ancelotti says Beckham could make his debut next week.
"I've never expected that wherever I have gone. I'll work hard for my place, I'll work hard to make the team successful," Beckham told beIN Sport this week.
"We'll see, I don't know (where I will play). I can either play in the middle or on the right.
"Goalkeeping's not my biggest strength so I'll stay out of the way of that one. I don't expect to come in to this team and to be a starter in the teamsheet."
