Gareth Bale will play the Cristiano Ronaldo role for Real Madrid on Saturday against Real Sociedad.
Ronaldo is on a two-match ban.
Bale has scored 11 goals in 11 matches when he plays without Ronaldo.
"[Bale] will change his position," Carlo Ancelotti said. "He will play on the left. I prefer to have James on the right wing. But we will play the same way. We will defend with a 4-4-2 and James will have a position further forward in attack. We are not going to change the system."
