Obertan is available again after missing the last two weeks with a toe infection wants to help get his side back on track after they suffered their only defeat of the season on Saturday going down 3-1 to Manchester City.
But Obertan is not too bothered about the defeat and looks forward to the visit to Old Trafford this weekend.
The Frenchman said: “It’ll be great to be on the pitch at Old Trafford again. Hopefully, we’ll get a result there – it would be really, really good.
“Our confidence is really high, and there’s no reason why we can’t go there and get a point, or even three, if we play like we have before.”
