Manchester United assistant boss Carlos Queiroz admits it's critical the players shake-off the disappointment of last week's FA Cup elimination by Portsmouth.

"We were very down after the Portsmouth game. It was a bad feeling because we felt the trophy escaped from our grasp," Queiroz told MUTV.

"There was a lot of frustration and sadness amongst the team and the staff. But the most important thing now is to show the right attitude, the Manchester United attitude and bounce back from what happened. We need to keep moving forward."

The Portuguese added: "We cannot rely and expect other teams to make mistakes in our favour. It is up to us to do our job.

"This is a crucial part of the season and there is no room for error on our part. Now is the time to deliver.

"We expect the best from our players - the best concentration, the best football and the best motivation. Everything needs to be perfect."
