I guess it's possible we might be using some of our transfer income to start negotiating new contracts with some of our current squad? It would make sense as we have a fair few out of contract in the summer.
As others have rightly pointed out until the new players have settled in and we've had a chance to watch them it's difficult to say if the squad has improved, As it stands before seeing them I'd say no.
Stephens looks to be the pick of the bunch and will hopefully prove to be a good replacement...
