The Gers take on the Scottish Premiership side in the League Cup on Tuesday.
The 23-year old has been a key figure in this season’s new-look Gers side, and feels that they have already passed several tough tests this campaign.
“I see a lot of people saying that we’ll see where we’re at come Tuesday but we’re not really bothered about that we’re just looking forward to the game,” said the former Bradford man.
“Hopefully if we keep doing what we can do then the result will take care of itself.
“Easter Road in the first game of the season was a test, Alloa on that plastic surface was a test and Queen of the South was a test – I’m hearing that every week and to be honest I’m not really bothered.
“We’ll go and do what we do and just look forward to the game and hopefully we’ll put on a performance that shuts a few people up,” he added.
Despite his claims to the contrary, Rangers’ first clash with top-flight opposition will be the focus of heavy scrutiny - and rightly so.
Warburton’s men have made a flying start to the season and the eyes of Scottish football will be on Ibrox on Tuesday to see if they can replicate their form against better quality opposition.
St. Johnstone currently sit seventh in the Scottish Premiership after a mixed start to the season which has seen them record two wins and two draws and lose four times, in their first eight fixtures.
They should, however, provide a stern test for the Gers and will give some indication of how the Ibrox club will fare in the top-flight next season.
