Ricky1985 Balogun's one of those players whose story might be something, but won't take place at Arsenal.
Balogun's refused a further loan, but if he hangs around he won't be first choice, and will also likely neither prove nor improve himself to the stage he becomes first choice. He'll therefore continue to be footloose and in this holding pattern. Flo wants to leave for exactly these reasons, he's a bit uppity but he's rational.
Nketiah's nothing special, but he both applies himself and is willing to be second string. Way I see it we upgrade him when we can with a striker whose reputation is established.
