Crystal Palace boss Patrick Vieira says they must have a strong mentality going to Manchester United today.
With 12 wins in their last 12 games at home, Vieira is aware that he is facing a Manchester United side in a rich vein of form.
They are in a really good period they are playing well, scoring a lot of goals," he said. But we played them recently and we went toe-to-toe against them. We worked very hard against them, we played some good football at times but if we want a positive result we have to raise the quality of the game.
It's about how we play for 95 minutes as a team to compete and we have to do that to take something from it.
[A strong mentality] should be a given for us as a football club and as a team. We have to concentrate, we have to be competitive, we have to have a really good game programme to challenge United.
We know how difficult it will be but again we have the attributes to play a really good game of football against them."
