Chelsea goalkeeper Thibaut Courtois has called on the board to spend big this summer.

After winning the FA Cup, the Belgian believes that Chelsea need to start spending larger transfer fees on targets in a bid to get back in the top four next season.

"I think so, with Manchester City and United spending and working," Courtois said.

"If we want to aim for the top, we should do the same - obviously within the limits of what's possible in the transfer market.

"It's going to be pretty crazy. Nowadays you spend £80million for a defender I think - it's crazy figure.

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