Chelsea coach sarri backs hazard to emerge as premier league top scorer

I think there may be some confusion here. Maurizio Sarri is a former Chelsea coach, not the current one. He managed Chelsea from July 2018 to June 2019.

Additionally, Eden Hazard left Chelsea in June 2019 to join Real Madrid, so it's not possible for Sarri to back him to emerge as Premier League top scorer, as he is no longer a Chelsea player.

If you're looking for information on current Chelsea coaches or players, I'd be happy to help with that!
