Manchester City boss Roberto Mancini denies they've surrendered a psychological edge to Manchester United after yesterday's defeat.
City blew a 2-0 lead to see United win the Community Shield 3-2 at Wembley.
"I don't think it has given United a mental edge but it will be important for us to know why we lost this game," he said.
"A top team doesn't always play well, but when we score two goals and go 2-0 up, we need to have a strong mentality.
"If we play another strong squad like United, or against someone like Real Madrid in the Champions League, we need to continue to play football.
"We need to stay high up the pitch, not go too deep like we did in the second half."
