The transfer window is closed but there are still free agents up for grabs.
As long as the player was unattached before the summer transfer deadline they can be signed and registered to play for a new club.

BurnleyExpress are claiming Celtic are now front runners for Republic of Ireland international, Robbie Brady.

Brady can play a number of positions and given the Hoops lack of depth could be a good short term option.

Brady left Burnley in the summer having spent the last five seasons with the English club.
He has 57 Irish caps to his name and has played 160 times in the English Premier League. Would he give the Hoops more experience on the pitch and in the dressing room?
It would all come down to wages and length of contract. Celtic should not be handing out anymore long term deals to players belies the age of 26-28. Brady is currently 29, under the circumstances a two year deal would suit the club but would it suit Brady who will likely be looking around knowing his next deal is probably his last big one.
