Warburton linked up with Rangers over the summer after leaving his role with Brentford, and the manager has told the Daily Mail how he was convinced to move to Ibrox.
Warburton said: “I have never been to an Old Firm game, but when I was thinking about the job my son showed me something on YouTube. Rangers fans singing their song at a Celtic match. James just said, "Dad, look at this. You have to go there". I had met with Rangers once already and was thinking things through but all the things in my head were moved to one side when I saw this footage.”
Warburton had already held talks with Rangers before being shown the video of the Old Firm derby, but it was the atmosphere of the game which convinced him to take over at Ibrox.
Celtic and Rangers may not like one another with their long-standing rivalry, but the Gers should be thankful that they have this relationship with Celtic having hired Warburton on the back of a video of an Old firm game.
And what an appointment Warburton has turned out to be.
Rangers currently sit top of the Scottish Championship, having lost just one game out of 13 in the league, with Warburton bringing a style of attacking football which has been a joy to behold.
He made a number of summer signings who have proven their worth in the division, and it is hard to imagine Rangers not getting back into the top flight at the end of this season.
The Gers are flying high in the league, and after being convinced to move to Ibrox by an Old Firm derby, Warburton should be taking part in one next season with his team back in the Premiership.
