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 think it's part of the process, we can't just look at the game shown by one player, we have to see them as a whole. Have we seen Chelsea play well now? I can't say that yet, to be honest. Joao Felix can show good performance if his team plays well, in the sense that he can't play alone. Graham Potter has yet to find a strategy that is truly implemented optimally by the players who are on the field, it also affects the performance of the players. He also recently joined Chelsea, so I still have high hopes for him.
