It’s obvious but we need defensive cover for key players like Ryan. Someone with premier league experience who can easily just slot in and make it look like there’s not much different. Someone that got pointed out to me who out of contract in the summer is Daniel Agger, a man with experience and quality at the back which he showed at Liverpool. I also agree with Smithy about Caulker, who now has enough experience and would work quite well as understudy.
We also need backup/replacement for Glenn, who at the end of next season will be 33. Witsel would be fantastic and work work very well with Imbula in the middle of the park. If not, we could look into maybe someone like Shelvey as a cheaper option. And obviously the academy is there, with players like Shenton and Lecygne coming through at CM.
Finally we need a top drawer striker, which is easier said than done. Ideally someone like Loic Remy would be a fantastic signing for our style of play. Although we could turn to Liverpool for a different option as they are looking to offload both Christian Benteke and Mario Ballotelli in the summer. But who knows what will happen
