Manchester United midfielder Park Ji-Sung believes he doesn't have long left at Old Trafford and would consider a move to another club in the next couple of years.
Park, 30, has won the Champions League and four Premier League titles during his six-years at United but does not know how long he has left at the top level.
The South Korean's contract expires at the end of the 2011-12 season and he has recently been linked with a move to La Liga duo Sevilla and Atletico.
Park, who quit international football following the 2011 Asian Cup to help extend his club career, says he has no immediate desire to leave Manchester but would like to play for another club before he retires.
"I won't be able to show my best after one or two years. I don't know how long I can stay at Manchester," Park is quoted as saying in the Daily Mirror. "I never thought about retirement but it's obvious that I don't have much time left as a player.
"According to circumstances, I might leave Manchester United and retire in another team."
Park joined United in a £4 million deal from Dutch side PSV Eindhoven in 2005 and has been a huge success in England.
