According to The Scottish Sun, Leeds United, Fulham and Brighton and Hove Albion scouted Rangers at Ibrox last week.
Rangers were in action against FC Porto at Ibrox in the Europa League last Thursday evening.
The report has claimed that Leeds and Fulham in the Championship in England, as well as Brighton in the Premier League had scouts at the game.
Both Leeds and Fulham are aiming to finish in the top two of the Championship table this season and clinch automatic promotion to the Premier League.
Rangers have some very good players, and both the West Yorkshire outfit and the London club will benefit from having them in their squad.
However, it is hard to see Rangers sell any of their best players in the January transfer window.
After all, Steven Gerrard’s side are very much in with a chance of winning the Scottish Premiership title this season, and could also find themselves in the Europa League knockout rounds.
