Just a glance tell me a few of them are free transfers/back ups, and most play outside of the PL, so what relevance does it have to my original point, do I need to qualify it with ‘PL clubs’? Henderson is mooted for 20-25m transfer after one good loan at Sheffield, 2 years on the bench and one decent season at Forest, Martinez went for 20m after one good season at Arsenal, Ramsdale went for 30m after getting relegated, Pickford went to Everton 6 years ago for 25m. There are bargains to be had, as always, but buying a starting GK nowadays even for non-top 6 clubs will cost you a fair chunk, unless you are willing to take a big risk, just look at Leicester’s goalie situation post Kasper Schmeichel.
I don’t claim to know what’s going on with De Gea, he’s expressed his wishes to stay publicly multiple times though, so clubs may feel it’s a waste of time to approach at this point. If talks break down and Mendes shops him around, it’s hardly outrageous that more than a few clubs, especially promoted/relegation fighters would be interested at £10m a year on a 2+1 deal, for instance.
