Chelsea boss Guus Hiddink says Matt Miazga still has it all to prove.

Hiddink felt the 4-0 win over Aston Villa was no test for the debutant.

"You'll have to consider him, let's say when the real good war is going on and see how he copes with that. But it is a good first step up for him," said Hiddink.

"He's come from a League where it is a bit naive. He has to cope with a little bit of shuffle and a little bit of pushing, where in other leagues the referees might give free kicks"
