Mark Warburton's men have already wrapped up the Scottish Championship title.
Martyn Waghorn has responded to claims that Rangers will receive a shock when they return to the Scottish Premiership next season by suggesting that the Gers have the ability to cause a few surprises of their own, the Daily Record reports.
The Light Blues have comfortably secured the Scottish Championship title and have knocked out three teams from the top flight on their way to the Scottish Cup final.
But while some have warned Mark Warburton's men not to expect things to be so easy next season, Waghorn has insisted that those who are doubting them could be in for a nasty surprise.
"Until you play us, you don't realise how good we actually are. Celtic and Dundee probably underestimated us a little bit," he told the Record.
"They have quality players but the way we play it is hard to get the ball back.
"We wear teams down and physically and mentally it is tough knowing you are going to chase the ball for 60-70 minutes of the game. Until teams do actually play us, they can't know our game."
While it is fair to say that the demands of facing better-quality opposition will be tougher than facing a top flight side every few weeks, they have proved by beating Kilmarnock and then Dundee in emphatic fashion that they have the quality to make an impression at the highest level.
And on top of that, the way that they dictated the game when they came up against their Old Firm rivals Celtic in the semi-final hinted that they have the potential to be contending near the top of the table.
