Manchester United striker Marcus Rashford is adamant they're capable of beating Manchester City on Sunday.
United host City as rank underdogs.
But Rashford insists: "There's always something special in the air in these games and the fans are there for us every time," he said. "It's a huge part of us winning this game, as we've seen in so many games, home and away. The fans played a huge part.
"There are moments in the game when your backs are against the wall and that's when the crowd can make all the difference and really push you on. Whether every fan knows that, I'm not sure, but for the players that's definitely how it works.
"You have to be confident. You have to trust your own abilities. But you also have to pay them respect. We have to be ready for when the little moments arrive in games such as this. We need to take those moments."
