Sir Alex Ferguson claimed Manchester City were lucky not to be on the end of a real hiding from his Manchester United side following Sunday's action-packed 4-3 derby win for the Red Devils.
Substitute Michael Owen's winner deep into stoppage-time broke City hearts but left Ferguson in jubilant mood.
The build-up to the match had been overshadowed by some verbal jousting between Ferguson and City counterpart Mark Hughes.
Former United striker Carlos Tevez also played for City following his controversial switch from Old Trafford to Eastlands during the summer.
"We could have had six or seven today," claimed Ferguson.
However, after mistakes from Ben Foster and Rio Ferdinand looked like costing United their chance of victory, Ferguson admitted his side had been a little fortunate.
He added: "The fact we made those mistakes probably made it the best derby game of all time.
"What would you rather have, a 6-0 win or the greatest derby of all time? I would prefer to win 6-0."
Speaking about big-spending City, he added: "Sometimes you have a noisy neighbour. You cannot do anything about that. They will always be noisy.
"You just have to get on with your life, put your television on and turn it up a bit louder. Today the players showed their form. That is the best answer of all."
