McCall’s current contract with the Gers runs out at the end of the season, and no new deal is in place.
According to Herald Scotland, Milton Keynes Dons manager Karl Robinson recently turned down the advances of Rangers.
Robinson has been in charge of MK Dons since 2010 and has just guided them to promotion to the English Championship.
While many managers would be concerned, McCall is not worried about such rumours, and has insisted that he is focused only on leading the Glasgow giants back to the Scottish Premiership.
"It would be interesting to hear where those reports came from,” the 50-year-old told STV.
"It's funny. Karl has done a terrific job but, two years ago when I was offered the Sheffield United job, apparently there were reports then that Karl had been linked with it too…
"I'm more than happy with what's going on behind the scenes. I'm being kept up to speed, so it wouldn't affect me in the slightest who is being rumoured for it, who has knocked it back. My full focus is on getting promotion.”
McCall took charge of Rangers in March and guided the Gers to the Scottish Championship playoffs.
The Scottish giants defeated Queen of the South 2-1 away from home at Palmerston Park in Dumfries in the first leg of the Premiership playoff quarter-final tie last weekend.
The second leg of the tie will be held at Ibrox in Glasgow tomorrow.
