Young, who won a penalty at Old Trafford last week against Queens Park Rangers, tumbled to the ground in the seventh minute at Old Trafford although contact appeared minimal.
Wayne Rooney duly fired the home side into the lead from 12 yards and Danny Welbeck doubled the Red Devils’ advantage just before half-time from close range.
Rooney then grabbed his second of the afternoon in the 73rd minute, before Nani struck in the 90th minute to add gloss to the scoreline.
“I think he [Young] played for the penalty,” said Ferguson. “He has definitely taken a fall, it was a dramatic fall and he overdid it – but it’s a penalty, no doubt about it.
“There could be twists and turns [in the title race] yet but I think the name of the game now is for us to enjoy ourselves, play like we did today and hopefully we’ll be alright.
“You can never get too confident in this game. My experience tells me that there’s always something that’s going to bite you in the bum. Hopefully we can avoid that. The name of the game is not to drop any more points.”
Meanwhile, United defender Rio Ferdinand insists that he and his team-mates are not keeping tabs on Manchester City’s fortunes after Roberto Mancini’s men sealed a 6-1 win at Norwich on Saturday.
“Wednesday’s [defeat by Wigan] was a blip, fair dues to Wigan they played well and we didn’t turn up but we had to put on performance and we did that,” said Ferdinand.
“We don’t really take [Manchester City’s result] into consideration. The pressure is always on us, from within, from the fans, the manager, the pressure to win is always there.
“We want to win every game. We don’t care where we win the title – it could be in the garden, as long as we win it.”
