Rooney reiterated the need to show his best form for his country in what has been a chequered international career after an explosive start highlighted by his performances at Euro 2004.
He said: "Am I unfulfilled at international level? That is fair. I haven't been at my best for England and that is something I'm desperate to put right.
"I think us as a team and as a country, we need to be more successful and better in tournament football."
He said: "I think things have gone well and been successful. At club level I've won nine trophies and the only thing missing is being successful and to win things with England.
"That is what we are aiming to do. There are new coaching staff and a lot of young players have come into the squad and the future is bright for us.
"If we keep working hard and working together, I'm sure we'll have a great chance in the future of being successful."
