We won't be signing anyone until we sell, that's been fairly obvious since we brought in Carlos. We had 26 players (now 25 with Trez gone) that need to be registered for a 25 man squad. We don't want to have players knocking about that aren't registered, because one, we'd be paying them Premier League wages to play U23 football and two, it would affect morale to have them around training unhappy with their situation.
The likeliest senior candidates to go seem to be AEG, Guilbert, Sanson, Luiz, Hause and Traore, in no particular order, but until one of them leaves, we won't sign anyone else to bloat the squad.
