Rangers are expected to challenge Celtic for the Scottish Premiership next season.
Rangers confirmed their return to the Scottish top flight this season as they won the Scottish Championship in Mark Warburton’s first campaign in charge.
They met Celtic earlier in the season in a Scottish Cup semi-final, with that fixture being used by many as a gauge of the distance between the two sides.
Rangers’ performance in that game shocked many, with suggestions now being that they can challenge the Hoops for the title on their return next season.
And Miller says that it cannot be any other way, as if they fail to compete then the Gers will be viewed as failures.
“My experience here is that you’re clear on what your job is. It’s to win the league,” he told the Daily Record.
“From the moment I came here, you were judged on winning the league. It will be the same next year. If we’re not challenging, we’re failures.”
If Rangers are to compete with Celtic for the title as early as next season there is no denying that they will need signings to do so.
Manager Mark Warburton has already made his move, securing Jordan Rossiter from Liverpool and Josh Windass and Matt Crooks from Accrington Stanley.
Both of those, as well as a reported move for Joey Barton, already signal his intent and perhaps a shot at the title is his aim, too.
