I'm not ruling it out blanketly, I said exceptions exist, but James Tarkowski and Christian Eriksen and can confidently say are not players who have slipped through the cracks. Andros Townsend is not the kind of slides seamlessly into a system player that we should be bringing in.
On the other part, I'll give you as many as you want from each team, I still don't think it ends up being super impressive without projecting out development of younger players. Without thinking too much you get something like:
Jose Sa
Trippier Tarkowski Coady Digne
Ndidi
Maddison Gallagher
Raphinha Vardy Zaha
And that team is decent but I'm not sure the defense is really that good (you can argue for about 10 CBs tbh) and the attack doesn't have anyone who starts for most any of the top seven sides at the minute even if it is pretty good.
You could certainly pick some of those out that I'd take even today but the point is you can't really put together a team by buying best of the rest and when you consider that a lot of those best aren't actually obtainable it makes that much worse of a strategy.
