Definitely should get more from this transfer. While he's turd in the Premier League, I think Championship clubs have come to realise he's one of the best players at their level after playing a massive role in getting us and then QPR promoted. Having him can only be a huge boost to reach the promised land where the big money is so something like a 2, 3m layout pales in comparison. What probably hiked up the interest this year is the number of teams chasing promotion this season. Which can only be good for us.
'Worst case senario' for the purchasing club - sell him off to a Championship club after they get promoted. Even if they make a loss, it wouldn't be too big.
