Chelsea were beaten 5-3 at Yankee Stadium in New York, two days after losing 4-3 in St Louis.
Barry, who scored the opening goal, said: "It was a great spectacle and the supporters turned out in great numbers again.
"It was about something other than the result. We've had a great few days. Fans here and in St Louis have watched two great games with lots of goals and lots of attacking football.
"I'm not sure our defensive coach will be too happy but it is great to see games like that.
