Park Ji-sung has demonstrated his commitment to Manchester United by rejecting the opportunity to represent South Korea at the Olympic Games in London this summer.
The 31-year-old has made 100 appearances for his country, but announced his retirement from international football last year following the Asia Cup in Qatar.
However, the Taegeuk Warriors had hoped to persuade Park to reconsider his decision and feature at the Olympics as one of the country's three over-age players.
Park, though, is focused on helping Manchester United to a 20th league triumph, and believes playing at London 2012 would distract him from his main objective.
"I was called but I had to say no," Park told Hungarian daily Nemzeti Sport. "I know how it is like at the Olympics because I was involved in Sydney (2000).
"I have also played in three World Cup finals and my best memory was the tournament in Japan and South Korea in 2002. Few could have thought that we could get to the semi-finals.
"I have 100 caps, but this period of my life is over for me. I want to concentrate on my club from now on.
"This is my seventh year at Old Trafford. I won four titles but I want to win the Premier League this year more than ever."
Park has made 27 appearances for the Red Devils this season and has contributed three goals while he remains as important to the United cause as ever.
The hard-working midfielder moved to Old Trafford from PSV Eindhoven in the summer of 2005, and has made 204 appearances in almost seven years with the club.
