Alasdair Gold has claimed it was because we had the maximum number of internationals out on loan so the only way he could move was a mutual termination, but I suspect you're also right as well as it was probably too late to actually arrange a proper transfer.
It's also said his contract with Atletico is only until the end of the season anyway which is obviously leading to speculation that we'll re-sign him on a free at the end of the season which I don't think will happen.
Nah, he’s not coming back.
Good luck to him though. Seems like a perfectly nice guy and good pro.
