This is the problem.
Havertz is held to a standard where he needs to live up to a 100M price tag right away, a level he quite frankly has never yet shown consistently, and because he's not able to do that yet, he's questioned and criticized every game. Meanwhile, Mount gets to run around, do nothing, take a few nice set pieces, flick his hair up and down, commit a foul after he's out of position, and Chelsea fans tell us how he's such a valuable midfielder. The level people say Havertz is struggling at is a higher level than the level some of you say Mount is playing very well at.
