I always like a bench of 1 keeper, 2 defenders, 1 defensive midfielder, 3 attacking options.
So 1 of the 3 attacking options, maybe alongside Zamora and Elvis. Of course, he has to earn that place.
All signings must be looked at as a group, and we do not choose the order they arrive in.
Hughton wants 4 more, and I suggest these are :
Striker
Right Winger
Left Winger
Central Defender.
In the context of the above arrivals, Harper is an excellent addition, and a great signing.
