When you look at how few players that have been brought in over the last several transfer window it’s obvious that we need at least four signings in January just to keep pace:
Haaland
Werner
McGinn
Phillips
Those players would also transform the team into a top four side again. Furthermore, they wouldn’t be that expensive (relative to today’s crazy market). I reckon they could be brought in for a net spend of around 100 million if want-away Pogba and a few other players are sold.
