They should pull out all the stops imo. With Pulisic, Sancho, Ziyech, RLC, Mount and CHO, we may finally have a creative attack force.
If we can sign someone like Ndidi, our midfield will be solid again. Having Kova, Kante and Jorginho gave us a good base. Just need to add more bite since RLC should be played more as an AM imo to help his longevity in the sport. We just need to have a midfield that can link attack to defense with a bit of bite. Barkley is done for me at the very top unless he steps up to a new level which is hardly the case.
Defense-wise, we need to refurbish it. Get a good keeper, a world class CB and a good LB.
So in short imo, we need Sancho, a CF, a CM like Ndidi, a CB, LB and GK. We might not get all of them in one window but if we sell the likes of Emerson, Willian, Pedro, Giroud, Christensen with Morata money coming in and the leftover Hazard money + the annual transfer budget + the unused transfer budget for this window, we can at least sign Sancho, a CF and a GK. We still have a lot of youth that can cover for the CB, LB and CM for the time being like Gallagher, Anjorin and whoever that breaks out next season.
