I feel like if anything Mudryk would scare off other premier league sides from paying a steep asking price for a promising young Ukrainian. Mudryk has potential sure, but at 23... I'd say he looks some way off a lot of other younger players who have potential and do offer more consistency and quality. Look at Palmer at Chelsea, for example. Less than half the price of Mudyrk... and he's 1.) looking like he's got more potential than Mudryk, 2.) is performing at a much higher level than Mudryk.
Not to say that Mudryk is a particularly bad player or anything - I just think he made a big step up and the prices Arsenal and Chelsea thought were reasonable now look like a massive overinflation in value; I think he's a player that sort of tells a cautionary tale to other clubs in England about spending over the odds on a player from that league and expecting the transition to be seemless.
It's not so much that I can't see us spending that much on one player. I think we'll be in for very few players this summer, assuming we keep our big names, and chances are the players we bring in will be very expensive. It's just that at 21 years old and in a position where we've already got several promising young players, some of whom have made their debuts this season... it doesn't really make sense to pay anywhere near that amount for a player that's likely going to need a lot of time to adapt to the league. Harvey Elliott, for instance, is only 20 years old - so he's younger. He plays in the same sort of position and role. And he's already got a shitload of appearances for us and is developing nicely this season. Does it make sense to spend a lot of money, slow his development (and the development of other younger players like Carvalho, Koumas, etc) when we've got other areas of the squad to address?
