Chelsea defender Kalidou Koulibaly knows he faces a massive test at Real Madrid tomorrow.

Koulibaly recognises his clash with Real captain Karim Benzema will be decisive in the Champions League quarterfinal first-leg.

He said: "I said this to newspapers about two or three years ago, he is the best striker in the world. It will be a tough game but I hope Chelsea will win and pass this test.

"It is our objective but it is going to be hard because they won the last Champions League. We believe in ourselves, in our team-mates and manager.

"I am happy for Benzema, he is a good example for the Muslim people that we can do Ramadan, score goals and be productive.

"I hope he continues to score, but not on Wednesday."
