The Gers boss suggests there is a gap between the Scottish Premiership and Championship and admits it may take promotion for his players to be recognised.
Rangers manager Mark Warburton has told reporters that he respects Scotland manager Gordon Strachan's decision on the national squad, but suggested his players may find it easier to win call-ups when they are back in the Scottish Premiership.
Star Gers players such as captain Lee Wallace and midfielder Barrie McKay have been left out of the squad for the upcoming friendly internationals, a decision which has prompted outcry from some Rangers staff and supporters.
Warburton insisted that Scotland's loss is his gain, but did suggest that the gap between the top two divisions in Scotland means his players are perhaps not being considered as seriously as they should be for a national team spot.
The 53-year-old told reporters: "From my point of view I'm delighted the players are with me, I want them here as they're performing exceptionally well. Lee has been first-class, he's the club captain, he's been outstanding for us in everything he's done so I'm delighted to have him here.
"It's really important we respect Gordon's decision, but I think there's a healthy gap at the moment [between Premiership and Championship level].
"I've got no doubts that the likes of Lee Wallace and a number of players in the squad can step up, and if it takes going to the Premier League to do that then so be it."
It is not likely to be a problem that Rangers players experience for much longer, with a return to the top flight after a four-year absence a virtual certainty.
The Gers are 14 points clear at the top of the Championship table with just eight matches remaining, and could have sealed promotion by the time they face Peterhead in the Challenge Cup final before the Scottish Cup semi-final clash with Celtic next month.
Rangers can take a huge stride towards the second division title with victory over second-place Falkirk on Friday night.
