The Gers have strolled to the Scottish Championship title and received credit for the style of play they have adopted.
Mark Warburton has explained that the warnings that he received that Brentford's style of play would never work in the Championship during his time at Griffin Park is what is giving him confidence that Rangers will be able to shine in the Scottish Premiership next season, the Daily Record reports.
In his first full season with the Bees - the club's first in the second tier for over two decades - the 53-year-old was able to lead the side into the play-off places despite being tipped by many to struggle due to their expansive style.
And while they ultimately missed out on play-off success, he suggested that the way that they defied those who doubted them is what is giving him belief that the Light Blues' style of play can lead them to success when they return to the top flight next term.
"We were told down south we can't play that way in the Championship because we would get eaten alive. Davie and I couldn't see that at all," he told the Record.
"We had a real go with Brentford and got knocked out of the play-offs by Middlesbrough after finishing fifth.
"It shows we can play this way. This group of players need to be challenged again and we need to strengthen as well, which is well documented, and we will.
"We have to recognise we might have to tweak the style and make sure we retain our shape because you get punished more at the higher level but I think you will agree there is no reason why we can't play the same way," he added.
Though the Gers' recent results have been disappointing, their success in the Scottish Championship, as well as the way that they have got the better of several Premiership sides this season - including Celtic - will give most of the squad plenty of confidence that they are not that far away from being able to compete at the highest level.
And while they will undoubtedly face a much more difficult task if they hope to be competing right towards the very top of the table, Warburton's ability to take a Brentford side that kept its free-flowing philosophy towards the top the season after promotion proves that it is possible that Rangers will be able to do the same.
