I think we might keep Holding as backup due to the bolded. A top striker, if we can find one that is willing to join, will be very expensive. Revamping our midfield is not going to be cheap either.
If we can't get a striker now in January, I think that is no surprise. However, we really ought to bring in a central midfielder. Here there are good options.
Agree. Signing someone like Djed Spence for right back and keeping Holding would help with that. I'm sure Saliba counts as home grown as well. Will Martinelli be a home grown player when he's of age?
