Thibaut Courtois has warned Roman Abramovich that he could leave Chelsea this summer unless big signings are made this summer.

Courtois wants Chelsea to spend big like Manchester United and Manchester City this summer.

“We’ll see after the World Cup whether I am a Chelsea player for next year,” Courtois said.

“You see how Manchester City and Manchester United are spending and working.

“If we want to aim for the top, we should do the same – obviously within the limits of what’s possible.

“We’ll see what’s going on and I am sure the board will do what needs to be done.”
