Nani is battling for his future at Manchester United.
The Manchester Evening News says Gabriel Obertan is putting Nani's United future under threat.
The surprise summer capture from Bordeaux could prove to be a £3m Sir Alex Ferguson bargain buy.
Nani has struggled to convince Reds fans and critics that he can be an Old Trafford fixture since his £18m move from Sporting Lisbon in 2007.
The Portuguese winger was hoping Cristiano Ronaldo's exit might open the door for him but, despite 10 starts, he has not grasped his chance.
Now 20-year-old Obertan aims to leapfrog him after overcoming the back injury he arrived from France with.
