I can only speak to your final point but Barca and Real have no money. Barca can't even register the players they've already signed. And of the teams that can probably afford him none of them need a centre back as they went with other options for various reasons.I do watch, and have watched them both for ages.
I just dont think Romeros is a good fit for the prem, Demiral for me would be a better fit.
Spurs are paying way over the odds.
Juve happy to get rid of him, and play Demiral instead.
If Romero was THIS good, then why only Spurs in for him !?! Barca & Real need defenders.
EDIT: I've barely ever seen Romero play, just saying that Spurs having an open run at him is not a sign he is poor, over priced etc
