Guardiola was delighted with the victory over one of his main rivals for the English Premier League title this coming season, but the City boss isn't getting too carried away.
Last season, Iheanacho, 20, struggled for playing time with the arrival of Guardiola and subsequent arrival of Brazil star Gabriel Jesus.
"The new players have come in and we know the kind of energy they have to give us a really good chance to fight for the titles", Guardiola added. We have a lot of midfield players.
"Players played 90 minutes and that is very good news before the start of the Premier League".
Despite Bravo's hard first season in English football, which saw him dropped after a series of costly errors, Guardiola said the 34-year-old still had a role to play.

With time fast running out, Michy Batshuayi thought he had restored parity for Chelsea but his goal was disallowed for offside. Chelsea's next game is the Community Shield against London rivals Arsenal at Wembley Stadium on Sunday, August 6.
"But I saw him in these three games and his spirit in the training sessions". I will see what is going to happen.
"I like to work with the guys who want to work with us".
"Still I'm waiting for a bad performance". We don't think "it's pre-season, we don't care" - we do care.
The ball then bounced straight at the feet of Diaz, who faked out the keeper to put him on the ground before his easy finish from close range to make it 3-0.
Midfielder Samir Nasri impressed against Tottenham, with his manager praising the 30-year-old's "unbelievable ability" and "special quality" - but the former France international's future still remains unclear.
"I'm so satisfied, especially in the last two games", Guardiola told the club's official website.
