William Gallas, a former Chelsea player, claimed that Graham Potter, the team's new manager, has already caused a "problem" with Raheem Sterling.

Gallas claims that playing Sterling outside of his position was a mistake on the part of the English coach.

Potter has only been in charge for one game since being named the new Blues manager a few weeks ago after Thomas Tuchel was fired.

The former Brighton manager chose to play Sterling on the left flank during the 1-1 Champions League draw with Red Bull Salzburg.

Gallas also claims that he does not comprehend the manager's reasoning for where to place Sterling on the field.

“That is a problem." "When I saw Sterling playing as a left wing-back, I didn’t understand it,” Gallas told Genting Casino.

It’s difficult for me to understand why he wants to experiment with something like this, especially in a Champions League game.

“You are playing at home and you put Cucurella as a centre-back, you put Fofana on the bench with Koulibaly and Chalobah on the bench, and you put Sterling as a left-wing back?" I don’t understand.

In the end, they didn’t have a good result; they drew 1-1. People will always judge the result, and the question is, why did he put those two players in those positions? "
