I mean it might be that Everton aren't going to budge on Branthwaite. Maybe we're looking at Onana instead now? I don't think they'll sell both.
Yoro looks like he's off to Madrid, we're blocked from signing Todibo, so who does that leave? De Ligt could be a great CB for us, but it would depend on the deal. The wages would have to be lowered, but for the life of me I don't think a player would ever do that. Look how often we get stung by situations like this with our players! If Bayern really want rid of him, then they'll either have to pay him off to go, or accept a lower transfer fee. Say we signed him for £20m and he kept his supposed £270k pw wages...I don't think that's too bad, given his age. Would still be a risk though.
I think if you can do that deal, potentially sign Onana, also sign a top young CB (not Yoro) to come in and get a few minutes here and there, or go on loan for a season or two (like Arsenal did with Saliba, who's now one of the better CBs in the league) then that would be a better transfer strategy than signing Branthwaite for £75m.
