Former Manchester United star Park Ji-Sung has retired from professional football at the age of 33.

Park ended his career at Dutch club PSV Eindhoven – where he was signed to Man United by Sir Alex Ferguson in 2005 – while on loan from Queens Park Rangers, stating knee problems meant he could no longer continue at the highest level.

During his time with the Red Devils, he won four Premier League titles as well as becoming the first ever Asian player to play in a Champions League final.

“I’m leaving with no regrets,” Park told BBC.

The 33-year-old was known for his tenacious work rate and stamina, becoming United’s ‘big game player’ in his seven-year stint at Old Trafford.

He also became the first Asian to captain Manchester United, taking the armband from Ryan Giggs in a 2005 Champions League fixture.

“I enjoyed playing football,” added Park.

“I have achieved more than I thought I would. I’m truly grateful for all the support I have received and I will live the rest of my life thinking how I can pay it back.”

The South Korean scored 27 goals in 205 appearances, winning 11 trophies at Man United before he joined QPR in 2012.
