“There is one thing the manager is preaching it to us day in day out – we just do what we do,” said Miller. “We turn up and play our game.
“If we play that way and create that level of chance in the last 12 games then I’ll be more than happy. We can’t create those sort of chances again and not score three or four goals.”
Miller made the comments following Rangers’ 1-1 draw with Alloa Athletic away from home in the Scottish Championship on Saturday afternoon.
The Gers had chances to win the match at the The Indodrill Stadium, but they had to settle for a point.
The Glasgow giants are still at the top of the Scottish Championship table, though. Rangers have picked up 60 points from 24 matches, eight points more than Hibernian, who have a game in hand.
Warburton’s side are favourites to win the league title and gain automatic promotion to the Scottish Premiership at the end of the season.
Rangers will return to action on Tuesday evening when they take on Kilmarnock away from home at Rugby Park in the Scottish Cup fifth-round replay.
Kilmarnock will head into the game on the back of a 2-0 victory over Motherwell away from home in the Scottish Premiership.
