Ashley Young says Manchester United thrive off being labelled as underdogs, reports SkySports.
United make the short trip across the city on their longest unbeaten run in the Premier League this season, after going four games without defeat.
"I feel it helps when anybody thinks that United are underdogs going into a game," Young told Sky Sports.
"We know what we've got here. The team and the staff here know what we're building on. I had every confidence that we would go out and win the game.
"After the draws we had, it was important for us to get back to winning ways. We said before the game that we had to be on the front foot, we had to start well - and we've done that in a lot of games.
"We've gone 1-0 up and not been able to see games out. On another day, I feel we could have got more but we had to defend as a team as well and be resilient."
