The Manchester United midfielder capped a fine individual display with the winner in a 2-1 victory over Liverpool at Old Trafford on Sunday.
The diving header was Park's third goal of the season and the Korean has set his sights on adding to his tally before the end of the campaign.

He told MUTV: 'It was a great feeling. Derby matches are very important games, so to score the winner in a derby is a fantastic feeling.
'Doing it in front of the Stretford End was unbelievable as well because you're right next to the fans' reaction. I was very happy.
'I want to score more goals for United and it doesn't matter who they are against. I know I should score more goals. I feel good scoring against the big teams like Arsenal, Milan and Liverpool, but I want to score more goals, hopefully I experience it more often.'
Park was outstanding in central midfield against AC Milan in the Champions League and against Rafa Benitez's Reds.

He was given a standing ovation when he was replaced by Paul Scholes late on and the 29-year-old added: 'I enjoy playing in the middle of midfield. I have experience playing there before for PSV Eindhoven and for the Korean national team. So, for me, it doesn't matter playing in the middle or on either wing.'
United are two points clear at the top of the Premier League after beating their fierce rivals on the day Chelsea were held to a draw at Blackburn.
Park said: 'There are seven league games left and if we win them all then we will win the title. So we need to concentrate and keep up our performance levels.
'We don't need to worry about Arsenal or Chelsea, because if we win our games then we will be champions. So that's why we need to concentrate on our performances and our games.'
