He still has a year left to run on his contract, so it's better for him to leave now, and Swindon to get £500,000 for him than for him to leave on a free transfer next summer.
Andy King said: He will probably end up moving in the summer and that will be a nightmare for this club - I cannot replace his goals.
"He has another year but there are parts in his contract that allow him to speak to people and the monetary terms in his deal mean the bids will come in.
"I know we've had a bid this week. He's 24 and feels he needs to move his career on,"
