Chelsea boss Thomas Tuchel says Reece James will revert to wing-back against Leeds United tomorrow.
Tuchel played James in midfield for their 3-3 draw at Champions League opponents Zenit St Petersburg in midweek.
He said, "Reecey will start as a wing-back.
"We will find another consolation, he helped us out. We took the match to see some things because imagine if something happens tomorrow to Jorgi and we need to have a solution and we wanted to see it in real life.
"We took the match in Zenit to check out Saul in a different position and Reecey for impact in the middle of the pitch. But there is no need tomorrow to try these things. He [James] will start as a wing-back."
