I'd prefer to ask their managers mate. I'd put a bet that Howe would take Romero, as would Emery (the defense you think is better as I mentioned has shipped 47 in 33), as would Nuno.
The Scum unfortunately probably have the best CB pairing in the league and Pool has VVD +1 (he makes anyone look better, kind of how King did).
Deki, VDV, Romero, Porro, Udogie (rumour is City is enquiring now), all would be in a consideration for top teams, and I'd argue Arsenal would have looked a lot better this season with Solanke than whatever pretender they put up front.
Fact is our system makes our parts less than the sum, Villa, Forest, Saudi Sportswashing Machine (out of your list), Brighton, Bournemouth, current version of Wolves are the exact opposite, the system makes the players look better. To highlight it, you put Burn and Schar in our backline and they would look like Dier and Sanchez, every flaw they have would be exposed.
