Erling Haaland scored a hat-trick with the impressive Oscar Bobb also on target as City put our Premier League rivals to the sword in fine fashion at the spectacular Ohio Stadium.
It was a hugely satisfying way to round off what has been a memorable two week stay in America with a host of young players catching the eye.
And also an excellent way to step up preparations ahead of next weekend’s Community Shield against Manchester United.

Reflecting both on the win in particular and tour in general, the City boss said it had been a productive fortnight with Bobb further illustrating his vast potential and James McAtee and Nico O’Reilly both pressing their individual claims too.
And Guardiola said the trip had also provided another vital opportunity to help spread the Club’s worldwide appeal and ever expanding fanbase.
“To play teams like Celtic, Milan and Barcelona and now Chelsea is very good because they challenge you,” the manager reflected.
“Every game was much better than the previous one. We played quite similar versus Barcelona, but the feelings were really good.
“Of course Kalvin grew, and Erling grew and Jack had two incredible games.
“Rico has been unbelievable and Oscar both unbelievable. Today McAtee made his potential as a football player, Nico O’Reilly the same played at a high level and they’re young. We’re happy because all the young players made some minutes with us.
“It was really good in terms of our Club for the brand, to see how many shirts are here, it’s amazing. I remember the first time and second season there were few in a blue shirt but now a lot.
“We want to win the games of course but if we lost or won nothing changes. Now the real preparation is the season starting in seven days, simple as that.”
The boss also reflected on the tour as a whole and said he was delighted how his side had helped entertain and thrill the American crowds across all four games of the trip.
“I want to give advice for the promoters. We lost 4-3 v Celtic, seven goals, 2-2 v Barca, 3-2 v Milan, six goals here, every game we scored good goals,” Pep pointed out.
“If they hire us for next season people will be happy because we score and concede a lot!
“The people enjoyed it, the stadium is really nice, to see it full and lots from Chelsea as well.
“Every is healthy, safe, we showed good spirit very tough opponents which is really good.”
