The England midfielder, who should face the United States in Wednesday evening's friendly, is focusing on improving his game for the 2008/09 campaign.
"I'm not going to reflect on anything," he said. "It's fabulous to get a reward for all the hard work you put in during the season, but for me that's in the past already and I'm looking to next season.
"I'm looking forward to improving on things I did wrong this season, we'll sign some new players and keep improving. That's my goal, I can look back when I'm finished football, but now's not the time. I'm excited about next season already."
After securing his second Champions League winner's medal in Moscow, Hargreaves revealed he celebrated it just the same as his first - quickly and quietly.
"It's gone for me, if I'm honest," he said. "When I won it with Bayern, I didn't even celebrate really. It was my first season that I had broken into the team, I didn't even have a picture with the cup. I didn't want the impression on the older players that I was greedy.
"For me it was a fabulous moment, to put so much energy into a game and come away a winner. Five, ten minutes after I was content."
