The 23-year-old France international's second-half brace helped United move six points clear of the relegation zone but the new boy is setting his sights on moving further up the table.
He said: "I am very happy, but we can't forget the fact that this was a team performance. The team worked together. I played well, but it was a team effort.
"We came away with three points as a team and I hope we can go away and continue to perform like that to climb up the Premier League as high as we possibly can.
"I gave 100 per cent, the very best I could. I was signed to do that, to give everything to fight from the first to the 90th minute.
"That's what I tried to do, even though it's not always easy. I went out there from the very first minute until the very last minute and worked as hard as I could."
"I'm settling in really well. When I am not training, I walk around the city and the supporters will come over and ask me for an autograph, and it makes me feel fantastic when that happens."
