#4 Jordan Pickford
It is important of course to point out that Jordan Pickford signed a new contract at Everton, extending it till 2024 but as it is often the case, when the giants come knocking at the door, contracts often crumble at the financial luring and they only tend to increase the value of the deal rather than extending the stay of the player.
Ever since he announced his potential to England with stellar performances wearing the Sunderland jersey, clubs were bound to keep an eye on him. In a heavy spending summer where Everton looked to turn the tide of their recruitment, Pickford was identified and signed for a great fee of €28.5 million and since then he's been one of the best players for the club.
Blessed with a terrific vision for distribution and a strong hand for reflexes and strength based saves, the Englishman isn't shy of showing off his flying skills. His ball playing ability and the relentless composure that he shows are qualities that any top club would happily spend for.
There's no release clause as such but Manchester United can swoop in on him for a pretty hefty bid. If looked at how Chelsea and Liverpool spent on their keepers Kepa and Alisson respectively, it may be deemed that United would have to do the same in the current market.
