Anthony Gordon is the exception rather than the rule.
Can you hand on heart state you'd recommend your 16 year old to sign for Everton over Chelsea?
But you can count on 2 hands the number of lads his age and under who have been sold for £40m up front, with add ons attached. So of course it's the exception. But it proves the theory, that we took a lad who honestly wouldnt have stood out in Chelsea's youth teams, and I got him to a CL team in 12 months.
As for what I'd recommend, youd have to look at the deal wouldnt you? But I'd probably avoid clubs where my lad was being farmed out on loan here there and everywhere, and want him to have a settled environment where he would get a chance to play in their first team. That would be more likely at Everton than Chelsea from what I can see.
