It must be quite a headache for them looking at this squad. If Edwards left because they were going away from the data model and its been allowed to continue for a number of years, where does that leave the current squad when reviewing what's in place.
The likes of Nunez, Gravenberch and Gakpo might look a bit odd under the data microscope and they might need to be a bit pragmatic in thier approach towards building a squad for the future. Each new signing might have to be a step towards the future squad rather than ripping it all up and starting again.
The new manager will need time as they take the squad forward step by step each window.
