Crystal Palace manager Patrick Vieira was gutted after Sunday's loss to Manchester United.

The Eagles had a few opportunities to score at Old Trafford but were ultimately undone by Fred's 77th minute strike.

"I'm disappointed - we gave them a tough game, we made it really difficult for them," Vieira told Match of the Day.

"At the end, conceding the goal, we are so disappointed. And we had the chance before [for Ayew], it is frustrating.

"When you get opportunities, you have to take them, and when you don't take them your are left vulnerable. I'm am disappointed for Jordan as he had a fantastic game. That is football.

"We need to change our mindset. How can we be more ruthless when we're in the opposition's box? That's something we have to work on."
