We would need someone to pay what we want for Hojbjerg, Hojbjerg to actually want to join that club, Chelsea to actually want to deal with us, Chelsea to accept a lot less than 50 odd million, Gallagher to want to come. That's a lot of things to happen in a couple of days!
Also, Sarr, Bentancur, Maddison are all back now and Bissouma will be soon too. Also Skipp, Hojbjerg back up and it doesn't really sound like a great idea to spend 40m + now when we could wait til the summer and get him for probably half that once he enters the last year of his contract, or just buy someone else that is currently not available mid season.
