Celtic have reportedly made a sensational move to land Tottenham keeper Joe Hart this summer.
Ange Postecoglou has faced some big calls so far this summer over who he chooses between the sticks, with Vasilis Barkas struggling for form.
Record Sport revealed last summer Celtic were keen on the stopper after he became a free agent following his departure from Burnley.
However, he opted for a move to Spurs but struggled for game time only earning appearances in the FA Cup and Europa League for the club.
Now Sky Italia transfer guru Fabrizio Romano states that Celtic have opened talks with the English Premier League side over a possible swoop this summer.
Negotiations are on-going as the Parkhead chiefs look to add strength to a problem position.
The 34-year-old has struggled to hold down a regular first-team spot since falling out of favour at Manchester City under Pep Guardiola.
He has spent time in Serie A with Torino as well as West Ham while losing his place in the England squad.
