This.
We are really lacking in depth, all across the park. We have a lot of players on the payroll who simply aren't good enough to contribute at PL level with any reliable consistency, which is terrifying when you think of the sheer volume of dead wood that has been tossed away in the last two or three summers.
Any injury to Doucouré or Allan would absolutely cripple us - just like they did last year. We need a decent 3rd CM, to allow for a regular rotation. If we have created the wiggle room to spend the money, I'd love to see us go for Kalvin Phillips in January (almost zero chance, I know) or, if we have to wait until the summer, McTominay from Utd. Given the financial straits we appear to be in however it will almost certainly have to be a loan, in which case a younger player with an option to buy would be a better move - one of the many names previously bandied about from the French League perhaps, someone with some genuine creativity to their game. Whatever we do in January re CM, we also need to buy another one in the summer because that's when Delph goes and his wages come off the books.
Not going to dwell on RB. We need a new one, that's it. Coleman can still do an occasional job in a rotation, but he's running on fumes.
We also need someone to rotate with Townsend on the right - there's simply no option in the squad to play in that area if he is injured. Ideally a younger player comes in with a view to genuinely challenging for the starting spot, and I say that as someone who has been impressed with Townsend thus far.
