Best available ,good record especially with youngsters. Hope he'll take no **** from the dressing room egos, and play his best players in their best positions. Eliminate the focus on possession, get everyone to understand which goal they they need to run towards, and then to put the ball in the net. With the useless "Football Directors "still in place, he will earn every penny he's paid to get a tune out of their idea of talent.
Getting rid of the dross like Garnacho, Delap, Neto, Tosin, Badashile,Fofana, Mudryk, Guiu, Gittens would be a good start. The big decision sell Fernandez or Palmer, they don't play well together. Both need to be in the same position, just behind the striker, where Fernandez nearly always plays and usually underperforms. Palmer has gone backwards trying to find somewhere he can play to his strengths.
All that to do before we address strikers and defenders.
I note Alonso will be called MANAGER. That's a good start , but will it happen or just be another season of washing toddlers nappies ??
