The Dark Blues are pushing for a loan move which would see the Northern Irishman make a return to the club. He also received interest from the then Championship club last season but stayed at Celtic where he was given a run in the team and put pen to paper on a new deal.
Last season the 23-year-old featured seven times, five of which were in the league, one in the Europa League and the other in the Scottish Cup Final victory that was delayed from the previous season.
Hazard was given these opportunities in the first team after both Barkas and Bain failed to impress, fans have mixed opinions on his performances between the sticks.
It is still unknown if Postecoglou is looking to bring a new keeper to Glasgow this summer, But letting Hazard go leaves two professional goalies. Could this hint that Celtic are preparing to welcome a new keeper which would see either Bain or Barkas slip to third choice?
