Last Saturday, United recovered from two goals down to win at Aston Villa and consolidate their place at the top of the Premier League. This weekend they head to Norwich, having won the corresponding fixture last term thanks to Ryan Giggs' injury-time effort.
Both are hallmarks of Ferguson's 26 years at Old Trafford and underline why United can never be written off in any situation. And whilst the Red Devils chief accepts there can be no guarantees of such positive outcomes from negative situations, he accepts the feelings generated by them are unique. "It does feel different," he said.
"The dressing room is different when you get these late goals, or you come from behind. It makes an impact because there is more excitement. We have experienced it many times and it is credit to the character of the club that we can do it."
Yet the warning is there. Amazingly, United have been behind in 11 games this season, including the Capital One Cup loss at Chelsea. On two other occasions they have not pulled it back, failures which cost precious points against Everton and Tottenham.
Ferguson cannot understand how it keeps happening. But he is acutely aware it needs to stop.
"You don't expect to be behind by two goals," he said. "It is not that we underestimate anyone, we just don't expect a Manchester United team to be two behind. You go into games believing you will be two ahead.
"It won't happen all the time. It is not a gimme that you can come back from two goals down. That is the area where hopefully we will improve. Hopefully we will defend better and not lose the advantage of what we experienced last week."
Ferguson has experienced enough difficult days at Norwich to accept nothing can be taken for granted there. And he senses a renewed belief amongst the Canaries after a tricky start to the campaign.
" Chris Hughton has done a good job at Norwich," said Ferguson. "He gathered experience from his time at Newcastle and did a great job at Birmingham last year. It has taken a bit of time but you can see he is stabilising his own team now."
