However, Ferguson did concede that Young was dramatic in his fall.
"I think he played for the penalty," said the Scot. "He has definitely taken a fall, it was a dramatic fall and he overdid it but it's a penalty definitely, no doubt about it."
Despite his side's five-point lead at the top of the Premier League table, Ferguson still thinks that they are not home and dry.
"There could be twist and turns along the way but we now need to enjoy ourselves," he added. "We can never be too confident, my experience says that something could come and bite you in the bum and we want to avoid that."
The Red Devils continue their campaign next Sunday at home to Everton.
