Yeah but think the contract has to be ended before the end of the window , which he is still contracted to us @ the moment.Doesn’t appear so:
Free agent - Wikipedia
en.m.wikipedia.org
‘Free agents do not have to be signed during the normal transfer window that is implemented in some countries' leagues. If they are signed by a team, the team signing them does not have to pay any fees – sometimes this is known as "a free transfer".’
So only available to Saudi / turkey until new year.
