Park is now in his seventh season with United, having played his part in numerous triumphs. The Korean ace is famed for his energy and creativity but he's also capable of scoring crucial goals when it counts, as Arsenal, Chelsea and Liverpool - among others - have all found to their cost. He's already off the mark in this campaign, netting one of the Reds' eight goals against the Gunners after coming on as substitute. Park has since started matches against Benfica and Leeds United as he adjusts to the new competition for wide positions provided by Ashley Young.
You could quiz him on any of the above topics, his retirement from international football, his lifestyle off the pitch, his hopes for 2011/12 and beyond… whatever you like.
You can post a question for Ji-sung Park during Thursday's live chat, or submit your question now in advance by logging into or registering with ManUtd.com. We’ll ask the midfielder as many of your questions as we can in the time available.
The fan whose question is considered to be the best by Ji will win a new United shirt signed by the man himself.
