Rangers star Miller is enjoying a run of good form.
Warburton said: “I’m delighted with Kenny. His quality in training, his attitude in training is first class and he's a great role model to younger players. But you have to work hard for your contract and Kenny did that so I am delighted for him. He is still hungry to play and the younger players in our squad learn from him when they watch him train every day.”
Miller started the season with many doubting his worth to Warburton’s new-look Rangers team.
His increased age made him stand out from the majority of the squad, with the manager preferring to sign young and energetic talents to play a brand of high energy attacking football.
And these doubts continued into the early weeks of the season, when the 36-year-old was struggling to find the back of the net and looked to be losing his place as one of Warburton’s starting players.
However, with the club going through a run of poor form, Miller was reincorporated into the team starting lineup, and has enjoyed a great run in front of goal.
He has managed five goals and three assists in his last five games, leading the Gers to six straight wins, and surely the Championship title.
Warburton has praised the veteran’s impact in the squad, and if Miller continues to perform as he has been in recent weeks, the striker is sure to still be excelling next season in the top flight.
