I don’t see what a pre season will achieve is that going to improve his touch??It depends what they think they can get out of him. If they think he's going to be a much better player with a season under his belt thats great but if they don't the short sighted thing would be to keep someone you know isn't good enough just for the sake of it instead of taking the money while its on offer.
He’s league 1 level technically, he’s all over the place. Get 70/80% of the fee back and we should sell in a heartbeat
