Warburton seems unfazed by Hibs' excellent run of form, and how it may dent Rangers' title hopes.
Mark Warburton has responded to claims by Alan Stubbs that Hibernian's title challenge will be keeping Rangers up at night, by suggesting that his players are not even speaking about their nearest rivals, The Scottish Sun reports.
The Gers' fantastic start to the campaign was brought to a halt by the Easter Road outfit in November, and Hibs' own unbeaten run - which now stretches 12 games - has put Stubbs' men just three points behind the Scottish Championship leaders.
Warburton had a sarcastic response when asked about Stubbs' suggestion that Hibs have caused major concern at Ibrox, before insisting that he is only focusing on his own side's form.
"Haven't slept for weeks," he joked.
"If they are mind games, then I think psychologists can retire and move on. Far from it. It's just a bit of banter, I'm sure.
"Do the players speak about Hibs? No. Seriously, there's no fuss from our point of view.
"Why would we? I use that word respect and it is no lack of respect to any team. But our focus is here.
"If other teams want to talk about Rangers, fantastic.
"Our focus is Rangers. All we are thinking about is Morton this weekend," he said.
Although Rangers dropping points in two of their last four league games would suggest that the momentum may just be turning towards Hibs slightly, two successive 4-0 victories in all competitions has confirmed that Warburton's men should remain heavy favourites to return to the Premiership automatically.
As well as the three-point cushion to their closest challengers, the Gers boast a defence that has conceded just nine times all season - one less than Hibs - and have comfortably the most ruthless attack in the division, having scored 15 more goals than third-place Falkirk.
With the top two set to face off once again before the end of the month, Stubbs will be hoping that they can bring themselves level with Rangers going into the new year, and really give Warburton something to be concerned about.
