Everton striker Romelu Lukaku has been linked with a return to Chelsea after leaving Stamford Bridge for Everton three years ago.
When asked if he could play with Lukaku at Chelsea, Diego Costa revealed he doesn’t know but he hopes Lukaku signs for Chelsea.
“I do not know, that’s a decision for the club,” Costa told Het Nieuwsblad.
“Of course Lukaku is a very big player who has played an impressive season. I hope he will have the possibility to sign at Chelsea because Chelsea is a unique club.”
