He's definitely got potential, yes. I think he needs a run of games in a settled side as he seemed to struggle to get going last season after being used more as a sub.
He got sent off twice in 5 games last season for ridiculous things like slapping someone and kicking out. So maybe struggles with frustration and sees red. Think he's on about 70k per week so not too ridiculous. I think he's worth a gamble for someone at our level.
