Rangers manager Mark Warburton celebrates winning the Scottish Championship
Warburton worked with Grigg at Championship club Brentford and rates the Northern Ireland international striker highly.
However, the Rangers boss has made it clear that he does not want to add the 25-year-old former Walsall and Brentford striker to his current squad.
“I worked with Will at Brentford, we signed Will at Brentford,” Warburton told Rangers TV, as quoted by Inside Futbol, when asked about the prospect of signing Grigg for Rangers in the summer transfer window.
“Will has had a fantastic season. He is not our player and he is not one who would be on Rangers’ (radar).”
Will Grigg had a fantastic season for Wigan during the 2015-16 season and was a key figure in their promotion back to the Championship.
The 24-year-old striker scored as many as 28 goals for Wigan, who returned to the second tier of English football as League One champions.
The former Brentford man was also included in the Northern Ireland squad for the ongoing 2016 European Championship in France.
Rangers will feature in the Scottish Premiership next season after winning the Scottish Championship title with ease during the 2016-17 campaign.
The Gers have been quite busy in the summer transfer window so far, signing Joey Barton and Clint Hill among others.
