We can't. La Liga would only allow us an out-of-window transfer if the estimated injury time were to be 5.5 months or longer. We are allowed to sign club-less players as long as we have room in the squad (We do) but between that and giving the spot to one of our youth players, i know the one I'd pick
They don't even know how long he will be out though !?
The word is 4 months minimum even then he will have to get fit for playing ...
