I would say he has certainly got the potential to take Tetavanos place next season and is imo already a better prospect than both Sangare and Lisone.
Sounds like he was the player who was looking to leave last year due to a lack of opportunities.
He is no Walmsley and has blown hot and cold. But he does have potential and he is English and not on quota.
2 year deal with a 1 year option either way is sensible.
