Each to their own, I’m not sure it works like that. For me to rate a player, he needs to impress ME. Not Pep, not Klopp, not Ten Hag. My impression of a player doesn’t need to be absolute - but it’s mine. It’s simply the impression that I got from watching them. If after watching decades of football you do not feel entitled to say whether you rate a player or not then heaven help us. The coaches can think what they want, good for them. This isn’t a maths test, this is sport. Being open minded, hopeful or optimistic is all natural as a fan of a team. But being honest with yourself and what you think is basic.When you are linked with a player, you take greater interest to analyze a player and see what he brings to the team. I mean it would be unrealistic to analyze every player you watch, more often that not it's just casual watching without any keen interest on one player, it's more on the team and the general flow of the game, unless you are watching the player you are interested in.
You don't even have to change your mind, there are people (like me) who don't rate Mount as highly as others do but then when you take into account which all clubs are trying to sign him then you should at least given some benefit of doubt and be more open to the thought that you might be wrong about the player and your casual watching of player didn't give you enough information to assess the player properly.
If you, as you say, don’t rate Mount as highly as others then that’s how you feel. I’m sure you have players that you DO rate. It’s not mandatory for a football observer to have the same view as Ten Hag or Klopp. This isn’t about dying on hills, if your watching over the next year causes you to now rate Mount higher then fantastic. But you, nor I, are ‘wrong’ for not rating Mount as highly as others.
