It's the spine of our team hasn't been right. We need, as a minimum, a good centre half and a good centre mid.
I don't think any of the players with expiring contracts should get an extension. And for the younger players who are now reaching 21/22 or so, if they aren't going to make it, then we need to move them on.
We need to let as many go as possible on top of those out of contract. Mina, Gomes, Allan, Gbamin, Nkounkou, Rondon should all be available. We can't allow players with some value to leave for free. The squad should be at least much smaller this summer, so we can add 3 or 4 without it becoming unmanageable. If we need to make a big sale to help the rebuild, then decide early who can leave and get as much money as possible, with replacements lined up.
