So, the transfer deadline has come and gone, and Celtic have only managed one signing.
Martin O'Neill was reported to have been looking at several players, but the only player to sign has been Michael Gray from Sunderland.
Gray has moved to Parkhead on a 4 month loan deal, which will see the Englishman at Parkhead until December.
Michael Gray is Sunderland's longest serving players, and has been capped 3 times for England. From what I hear he is a decent player and will do no harm to Martin O'Neill's squad.
