Obertan has failed to find much form since his £3.5m move from Manchester United last season, despite numerous chances.
He was forced to play as an over-age player for the club’s Under-21 side last night against Crystal Palace, but responded witha treble in a 4-0 win.
Gabriel Obertan: “That’s very good for the confidence.
“I’ve been kind of dropped from the first team and it’s good to play with a young, enthusiastic team so I’m very pleased.
“I just enjoyed the game. Of course it’s been a while since I played in any competition, so even if it’s a reserve game you still have to put your work into it.
“The coaches helped me a lot, Peter and Willie, so it’s been a great time for the team.
“I’m trying to work hard for myself, to stay fit and be ready for whatever happens.”
Rolando Aarons got the other goal.
