The Manchester United midfielder finally made his long-awaited comeback from double knee surgery as a substitute in the final minute of the 1-0 win over Sunderland on Sunday.
Back in black: Owen Hargreaves in action against Sunderland on Sunday
Hargreaves is unlikely to feature in the crunch final-day clash with Stoke that could decide if they win the title but he is determined to be back properly in August.
Good to be back: Owen
He said: 'I've missed two seasons and I'm disappointed about that. But I'm 29 and hopefully I've got another six to eight years left in me.
'Being out for so long is obviously not something I would have envisaged myself going through. It's been a learning experience and I try and take the positives from it.
'It was short against Sunderland but obviously I'm looking forward to next season. We've got our last game this weekend [against Stoke] and hopefully I'll play a bit again, and then hopefully get ready to attack next season.'
Hargreaves would have been a serious contender for the World Cup but England boss Fabio Capello is unlikely to consider taking such an injury-prone player to South Africa.
