Chelsea legend Ashley Cole says they must fight to keep hold of Toni Rudiger.

Rudiger was on the scoresheet as Chelsea beat Tottenham 1-0 on the night and 3-0 on aggregate to progress to the final of the Carabao Cup.

The centre-back is a key part of Thomas Tuchel's team, but his future at Stamford Bridge is uncertain given that his contract expires in the summer.

Speaking on Sky Sports, Cole said: "Rudiger was brilliant. You can't lose top, top key players in this dressing room. I think he can do everything.

"He can play out from the back, he can start attacks, he doesn't like to be beat one v one, so he puts his body on the line. He's becoming a real leader. He's temperamental at times."
