Chelsea boss Maurizio Sarri was delighted with two-goal Eden Hazard after victory over West Ham.
The Belgium international netted a brace in the Blues' victory, moving them back into third in the Premier League table with just five games left to play.
Sarri spoke out about the transfer speculation around Hazard.
He said: "I don't know, I am not the club, I can't do anything to answer. I can't answer. [Can we lose him?] From the technical point of view, no not at the moment.
"There is no other Hazard because the level is so high. I hope Hazard can stay.
"The club doesn't want to sell him but we must all respect his decision I think. He is in the last year of his contract and if he has another decision then we have to respect it. We tried but it is not easy."
