His season-long loan at Celtic has hardly been a crushing success and only last week manager Neil Lennon managed to omit his name when discussing the future of his loan players.
Talk about the writing being writ large across the wall.
And Celtic fans regularly take to their keyboards to let the world know what they think of the Austrian international.
And now Football Insider say their `sources’ believe Lennon is set to turn his back on the option to buy Bauer.
Well who’d have guessed?
All of which leaves Stoke with the problem once again of what to do next with Bauer when he returns to their doorstep.
Does manager Michael O’Neill keep his options open by taking his first look at Bauer at close quarters and then decide if he is worth another shot at Stoke?
Or does he turn round to both player and club straight away and urge them to set up another loan move, or even a permanent deal if one can be had?
O’Neill is hardly struggling for numbers at right back after seeing Tommy Smith belatedly impose himself on the position following his move from Huddersfield last summer.
And plenty will be hoping to see Tom Edwards come again and put pressure on Smith for a first-team jersey.
Bauer’s energy and attacking instincts would suit O’Neill’s definition of the right-back role, but he might find his lack of defensive nous harder to stomach.
If he is stuck with him long term, perhaps right midfield becomes an option?
