I think it will be alright tbh I'd be more pissed off if Murray went on the cheap/free. It looks like we will get a lot of money, we do have Noone to give some width and hopefully KLL coming back. The spine of the team is excellent, great defence, solid midfield and Murray upfront. If Murray left then I'd be really worried about who is going to score the goals.
You do know most wingers get subbed in the 2nd half of matches due to fitness levels? Bennett is super fit who has played in nearly every match and for 90 mins.Noone isn't even close to Bennett yet.
We sell Bennett now i doubt we will find another player like him for quite some time. Then you have to find a replacement,give him time to settle in.Coach him to play Poyet's style which all takes time.This is why pre-season is so important to Gus and other managers.
