Andy Halliday has praised the contribution of all three substitutes during Rangers' win over Dundee, but reserved a special mention for Barrie McKay's display after he came on during the game at Ibrox, the club's official website reports.
The Gers maintained their position in third place in the Scottish Premiership table, but only after a Harry Forrester goal in stoppage-time saw them secure a narrow win over Paul Hartley's men.
And with Forrester being one of the men that Mark Warburton brought on during the second-half, along with Joe Dodoo - who bagged the assist for the winner - and McKay, Halliday suggested that the trio were vital to the Light Blues securing the three points.
"It must be disappointing for the likes of Joe Dodoo and Harry not to be starting because they are great boys and work hard every single day in training," he told the club's official website.
Rangers' Harry Forrester
"Harry started the season in bursting form and maybe a wee dip in form and some niggling injuries have kept him out of the team but to come back and score a goal in the last minute is fantastic to him.
"It was a great ball in from Joe and I thought Barrie changed the game when he came on, he added that injection of pace."
The way that the substitutions paid off will surely provide Warburton with a tremendous sense of satisfaction. With the team going into the international break having failed to beat Ross County, there were perhaps some beginning to question whether the former Brentford boss was the right man to lead them forward and back into the title picture.
Halliday labelled McKay a game-changer
And those who were sceptical about Warburton's future would arguably have been forgiven for questioning his decisions to take Josh Windass, Michael O'Halloran and Kenny Miller off.
Windass can bring a level of creativity that few in the squad can match, while O'Halloran has arguably looked a much better player during this recent run and Miller is their joint top goalscorer in the league.
But the contributions that Forrester, McKay and Dodoo made completely vindicated Warburton's calls, so may have perhaps left some of the doubters much more convinced about his credentials.
