The guard of honour has become tradition in football after a team wins a league.
Some see it as a show of respect, a recognition of a rival’s achievement.
Others, meanwhile, view it as unnecessary, that the trophy and medals should be enough.
Chris Sutton sparked the debate by claiming Rangers should give Celtic a guard of honour next Sunday after the Hoops clinched the title against Aberdeen on Saturday.
Ibrox supporters reacted angrily, with many tweeting that they would walk out of the stadium if one was formed. The guard of honour is a regular occurrence in the modern era but has happened as far back as 1955 when Manchester United gave one to Chelsea.
Last season, Hearts marked Brendan Rodgers' title success while Aberdeen, Ross County and various other clubs have provided them during the eight in a row run.
It remains to be seen whether Rangers will have one for Celtic at Ibrox, but it isn't something they have to do if they choose not to.
In 2016 when Rangers won the Championship, they played Hibs three days later at Easter Road but Alan Stubbs' side didn't give Mark Warburton’s side one. Ibrox skipper James Tavernier was to later criticise their decision in a tweet following Alloa's guard of honour for his side.
Tavernier had tweeted: "Great respect to @ AlloaAthleticFC for the guard of honour today!! True sportsmanship unlike some!!"
At the time, Stubbs had said he wasn't getting involved in the debate and revealed he honoured Rangers by phoning Warburton and David Weir to congratulate them.
During Alloa's show of respect for Rangers, they had a Celtic loanee in their side. Michael Duffy had been on a short term deal at the Wasps and kept his hands behind his back while his team-mates applauded Rangers on to the pitch.
Explaining his decision, he said: "There’s nothing much else to it really. I play for Celtic, so that’s the only real reason I did it.
"I’m sure it will all die down after a while but it’s funny to see everyone go mad about it. It’s just the way it is being a Celtic player.
"There probably wouldn’t have been that much of a deal made about it if Rangers had won."
Elsewhere, Real Madrid and Barcelona have both refused 'pasillos' in recent years. Barcelona first declined in 2017 when Real Madrid had won the Club World Championship, and the Bernabeu club returned the "favour" six months later when the Catalan giants had won La Liga.
