Chelsea midfielder Mateo Kovacic is convinced by the commitment of Eden Hazard.

Kovacic is on-loan at Chelsea from Real Madrid, which are being linked with Hazard.

"For me, he is an incredible player," said Kovacic.

"I did not know he was that good and he can easily be one of the two or three best players in the world.

"He asked me how it was there (at Real) but we are looking forward to having a great season together, to be fully concentrated on Chelsea.

"He is focused a lot on doing great things with Chelsea."
