Fulham manager Mark Hughes does not expect Manchester United to take their eye off the ball in Saturday's Barclays Premier League clash at Old Trafford, but will be ready to exploit any opportunity if they do.
With United still fighting on all three fronts, it is likely Ferguson will rotate his squad against the Cottagers, who have been beaten nine times away this season. However, Hughes believes his old club will not lose any focus as they look to extend their seven-point lead over Arsenal at the top of the table.
"Past experience suggests that won't be, but we have got to be ready if they are not on their A game. If they are not then we have a chance to win the game. We are looking to be positive," said Hughes, whose men have moved away from the relegation zone following a run of just two defeats in the last 11 Premier League games.
"We are playing well, so why not have a go? If their eye is off the ball, then maybe we can exploit that.
"In terms of the schedule they have got at the moment, with the high-profile games, we can't really say what players we will be facing, but they will be accomplished players.
"It is about managing your resources and Sir Alex (Ferguson) has been the best for a long time at picking the right team for the right game, so we know we are in for a big test.
"Their home form has been exemplary. Only one team has been able to go there and get a draw, but we want to do better than that if we can."
Hughes, who had two successful spells at Old Trafford as a player, believes his old club continue to show the true spirit of champions, while other sides like Arsenal and Chelsea fail to make the most of any opportunities presented.
"As the season progresses towards the business end, United are getting stronger and stronger," said the 47-year-old former Wales manager. "They understand exactly what needs to be done and are going about their business in a fantastic manner and sweeping everyone aside.
"Against West Ham, they found themselves in a difficult situation, but they did not panic, got on with their job and turned things around, because they have the mentality and a manager who demands that of them."
