The world number one, pounded out of the fourth round of this year's tournament by big-serving Australian Mark Philippoussis 6-3, 2-6, 6-7, 6-3, 6-4 on Monday, had no hesitation when asked about his future plans.

"Why shouldn't I be back. I'm a tennis player. My plan is to be back next year," Agassi said.

The American, who won Wimbledon in 1992 and the last of his eight Grand Slam titles in Melbourne in January, said victories grew sweeter with age and defeats more disappointing.

"They get more disappointing but it doesn't last as long," Agassi said.

"It's disappointing because it's another year lost at Wimbledon," said Agassi, who chose not play at the grasscourt tournament for three years from 1988.

"As you get older you are aware of how short-term all those opportunities are...

"But...you go home to your boy, you go home to your life ... I try to keep it in perspective."

Agassi is married to seven-times former Wimbledon champion Steffi Graf, has an 18-month-old son and the couple are expecting a second child later this year.

Agassi said only a few points on Monday separated himself and Philippoussis, who banged down 46 aces against the best returner in the game.

"So little can decide each set. There were a lot of moments when either one of us could have won ... he ended up being the one to take the opportunities in the end," Agassi added.
