Personally, I'm not writing him off but it's clear that there are fans who seem to overhype/overrate him way beyond his current abilities right now.
Am not one to just stupidly dismiss chances created from corners or take it for granted, especially after having witnessed Willian taking them for years, but think Mount being in Top 5 for chances created is kinda misleading. I don't have the exact numbers right now but how many chances has Mount created from open play and how many from set pieces? The ability to create chances for open play and the ability to create chances from set pieces are two different things. The former is the one that separates the best from the rest. That's down to a player's vision, creativity, passing and that knack of picking out passes that not many others can. The latter is down to basically accuracy of the delivery more than anything else from a dead ball situation. It's good that Mount is good and improving on set pieces but what we want to see from him is to creating chances from open play. Why do you think people praise players like De Bruyne, David Silva, Fabregas, Xavi, Iniesta etc? It's because of their ability on the ball and ability to create chances from open play. It's not because of chances created from set pieces.
And yes, that James opportunity is valid and he should have scored but that's just 1 example from the game. One could easily pick out a moment like that from Willian but no one will sit here and say he's creative, no?
How is Mount not having end product nonsense? Lampard spoke about it a lot - e.g. wanting him to get into the box more and score more goals - and Tuchel mentioned after the Southampton as well, saying Mount did a lot of good things to create dangerous moments but the final ball was lacking. Even Mount has said it himself before.
Mount is playing a lot because he does the other stuff right - e.g. the effort, the energy, tactical reasons - but it's clear that his end product isn't there. Mount leading by example with the performances is totally different from having no end product.
Mount is decent right now and may well go to become a great player but if this Mount had come through the academy at another club, would we go gaga and want to buy him for say 30, 40, 50 million now? And also, if by miracle everyone in the team is fit and firing, would Mount start ahead of CHO, Pulisic, Ziyech, Havertz under Tuchel?
