At £25 million and a huge upgrade on all of Bailly, Jones and Rojo I guess it’s a no brainer. He seems to be over his injury prone questions, experienced, proven in our league, Champions League experience and at 30 allows a year or two for Tuanzebe to develop.
We could get £20-£25 million for Bailly and similar for Rojo even though neither are as good so I’d sell them both and go with Alderweireld, Lindelof, Smalling, Tuanzebe and Jones (as 5th choice) as our centre back options for next season.
Spending only £25 million leaves a lot for a full back, defensive midfielder and a right sided forward especially with sales/releases too. I think De Ligt is Barca bound and Militao is on his way to Real so with Koulibaly signing a new contract recently I’d say Alderweireld is the best option that’s realistic.
