The Celtic goalkeeper, Scott Bain, has indirectly urged the Bhoys to re-sign Oliver Burke from West Bromwich Albion.
Burke spent the second half of last season at loan to Celtic, for whom he scored or made seven goals in 19 games.
But he is due back at West Brom for pre-season training, unsure what the future holds for him at either club.
Both Celtic and West Brom have experienced a change of manager since Burke's January move north, with Neil Lennon and Slaven Bilic replacing Brendan Rodgers and Darren Moore, respectively.
But if Bain had his way, the English-born Scotland international would be back at Celtic Park.
He shared the following picture of the pair together in the early hours of Friday, along with the message: "Left this guy a minute!!! Bring um back!!!"
West Brom are reported to have paid around £13.7 million to sign Burke from RB Leipzig two years ago.
That is the same amount Nottingham Forest received for the Reds academy product the previous summer.
Should Celtic bring back Burke next season?
