Talking of helping the club I'm overall, is the club helping him at all? Currently, I will say it's Joao Felix if any one asks me who is doing undoubtedly well for chelsea. Joao Felix will offer more than he shows if t all other players best is as good as joao's. If u doubt it, count his contribution per match and compare it to every other attacker.
Some people have suggested that Joao Felix will play better as the top striker for Chelsea, but I do not agree with them because watching Felix play, he does better running from the midfield towards goal than being placed at the center as the main striker. Havertz has not been impressive, but there is something about him that offers hope, but still I think Chelsea another pure striker since they are into the buying business, they need a new coach as well, that is very obvious by now.
I do not know for how long the Chelsea owner is going to continue with this coach. This is certainly getting a little out of hand. The performance of Chelsea is not good. And you don't have to be an expert to understand that. Every football fan, actually, even if you are not a fan, will understand that Chelsea is not performing well and the main reason behind that is the coach. And as long as that is not getting fixed, Chelsea will not be able to perform better. Doesn't matter how much money they spend. Probably the owner does not even know what ROI is. And probably he's also prepared to lose everything to keep this coach.
