Please. He was never their best player. Not even close. Also, by your metric, the same rule applies for how shit Chelsea were - he won his second POTY as one of the better players of a bad bunch. Hardly a good benchmark. His POTY's are an example of nepotism at it's finest, being one of their own. Additionally, recency is a real thing in football. Dele Alli was twice young premier league player of the year, remember. Does he get special dispensation for 'outliers'? Do some of our players get excluded from the 'shit-basket' for how poor we've been? Or just Mount as he's our shiny new signing?
Mount has been playing for 4 years. Last 18 months he has been, unarguably, pretty shit (cue excuses about how bad Chelsea were, manager changes, etc.), and in his first season he played 53 times and managed 8 goals and 6 assists - which isn't exactly a stellar return for a #10. So if we remove his debut season and the last 18 months, that leaves how much left over from 4 seasons? So if we're looking at his career, as a whole, he's average, at best. And don't get me started on how he's performed, so far, for United. . . . Hardly a signing to get excited about; and most definitely not a signing that we should have prioritised to the detriment of other signings - especially for 55m in the final year of his contract.
