City beaten in Inter friendly
Obinna opened the scoring in the 38th minute and fired a shot in the 54th minute that deflected off the leg of City defender Joleon Lescott and into the net for the Italian's second. Cristiano Biraghi made it three in the 74th minute, blasting home a 35-metre shot into the top left-hand corner of the goal.
"I am really pleased with the performance of the team. They played really well," said Inter manager Rafael Benitez. "Our idea is to improve our fitness and also give time to our young players on the pitch. We got to do both."
Manchester City, who open their Premier League campaign against Tottenham in two weeks, were without manager Roberto Mancini, who departed Friday because of a family illness and was replaced by assistant Brian Kidd.
They went down a man in the 21st minute when France international Patrick Vieira was given a red card for a foul on Marco Materazzi. "Pat was going for the ball," Kidd said. "It's difficult for the referees. It's split-second. But there was no intent there."
City, playing the final match of a pre-season US tour, used reserve goalkeeper Joe Hart in the first half before replacing him with Shay Given for the second. "Certainly playing a man down was too hard too overcome," Given said.
