Jury's out for me mate. 6 of those goals have either come against lower league opposition in the cups or for their under 23 side.
He had a decent season last year for Marseille but not what I would call prolific in an inferior league. I was surprised that Chelsea paid so much for him in the summer and obviously Conte doesn't fancy him as he's played Hazard in a more forward role when Costa wasn't available.
I'm not saying he doesn't have it in him to succeed in Premier mate, but unlike other options we may have, he's never been prolific at lower levels, and 587 minutes football this season when the clocks have already gone forward suggests he is not held in high regard at Chelsea.
To be fair to the lad I've never really seen him play much and I'd have to trust in Walsh/Koeman's judgement if we were after him.
