I like Erwin a lot and can see his potential but he's not played one full season for us and has scored one goal. I can't see why Brighton would come in just now when he's out of contract in the summer.
For the player himself, he needs games. I reckon he'll get them here, irrespective of who we bring in today. If I were the club, I'd be asking him to sign a new contract with the understanding that when a decent offer comes in where he thinks he'll play and develop, we won't stand in his way. Jamie Murphy waited and is playing every week for a bigger club than Brighton...
