I don't care about all that. Poulsen is not needed here. Discussing the past is irrelevant and doesn't solve anything. He earns too much and does too little, and is fourth/fifth midfielder in starting order.
I don't know if he'll be a great player, but he's proven so far that he can be a good utility squad player like Iaquinta. And we could use someone like that right now instead of dead weights like Poulsen, Tiago, De Ceglie, Sali, etc.
