Manchester United manager Louis van Gaal has warned his players that they will face a "very tough game" when they travel to Norwich City on Saturday lunchtime.
The Canaries, who are in the relegation zone, have picked up just two wins from their eight home matches in 2016.
Nevertheless, Van Gaal has insisted that United cannot afford to take their hosts lightly at Carrow Road.
"It is always difficult to fight against a team who fights to maintain their place in the Premier League. That is always very difficult," he told reporters.
"That is no excuse; we have to cope with that. Norwich won at Old Trafford so we have to take revenge. It shall be a very tough game, but in spite of that we have to win."
United go into the clash in fifth position, four points adrift of the Champions League places.
