Artur Boruc has been pictured at Ibrox as Legia Warsaw leading fans chants with a megaphone.
The ‘Holy Goalie’ is a massive Legia fan and was seen cheering his team on at a ground he knows well.
The Polish star, who was a hugely popular figure during his five years at Celtic, never backed down at the stadium in the face of sectarian animosity.
Tonight, Legia fans trolled the hosts, who have been charged with racist and sectarian chanting after their trip to Warsaw, by unfurling a banner of Pope John Paul II.
Below the picture of the Polish pontiff was the message: “We are not afraid”.
Dozens of flares were also set off causing the match to be suspended until the smoke cleared.
Rangers, who are in court more than Andy Murray these days, might find themselves in hot water with UEFA again as a result.
Failing to prevent them being taken into the stadium and set off could well see another charge coming their way.
Clubs have been charged by UEFA in the past for failing to control opposition fans.
Arsenal were charged with ‘insufficient organisation’ after Galatasary fans ripped up chairs and lit flares at the Emirates in 2014, but were subsequently cleared.
Rangers won the match 1-0 with a late goal from Alfredo Morelos.
