Manager Sir Alex Ferguson has hailed Manchester United's character and admitted their latest comebacks have been exciting.
Last Saturday, the Premier League leaders recovered from two goals down to triumph at Aston Villa and they head to Norwich this weekend, having won last season's corresponding fixture with a last-gasp strike by Ryan Giggs.
Despite his team's defensive frailities, the relentless attacking force has delighted the boss and Ferguson 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.
"You don't expect to be behind by two goals. 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."
