City's squad are now dispersing for the summer - although some still have international commitments - after completing their post-season tour of the United States with a second successive win over Chelsea.
When they return for pre-season training they will be greeted by a new manager with Malaga's outgoing boss Manuel Pellegrini expected to be confirmed as Roberto Mancini's successor in the coming weeks.
The sacking of Mancini a fortnight ago after a year of relative under-achievement cast a shadow over the closing week of the season.
But City have successfully lifted spirits during a positive trip to the US and Barry feels confidence is restored.
The 32-year-old said: "We're disappointed with the overall finishing position in the league and to lose the FA Cup final but you can't win them all.
"You have to learn and we have to come back fighting strong for next season.
"The lads are already looking forward to it.
"The club needs to keep winning trophies. We've had a disappointing season in not picking one up but if we can keep setting high standards the club will move forward and, as a team, we will move forward."
During the week-long trip to the US, chief executive Ferran Soriano has publicly mapped out the club's ambitious plans for the future and dropped hints that Pellegrini will soon be installed.
