Park Ji-sung admits it was a 'fantastic feeling' to score the winner against Liverpool as Sir Alex Ferguson reiterated Manchester United did not sign the South Korean purely to sell shirts.
United returned to the top of the Premier League table on Sunday as Park's second-half diving header secured a hard-fought 2-1 home win over Liverpool.
The midfielder, who has become an increasingly important figure in big matches for United, was delighted to make an impact in such a vital game.
And, having also scored against Arsenal and AC Milan recently, Park is now determined to improve his goals output after netting 15 times since his 2005 arrival from PSV Eindhoven.
"It was a great feeling to score against Liverpool," he said.
"Derby matches are very important games, so to score the winner in one is a fantastic feeling. Doing it in front of the Stretford End was unbelievable.
"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 that experience more often."
Upon joining United almost five years ago from PSV, Park's signing was mooted as a means for the Premier League champions to exploit the lucrative Far East market.
But United boss Ferguson was never in any doubt that the 29-year-old could become a valuable player for the club on the pitch.
Ferguson said: "I didn't think that (Park was bought just to sell shirts).
"When I went to see him play in those Champions League semi-finals for PSV Eindhoven in 2005 I thought this is a player who understands football.
"He is intelligent and disciplined and he can play different positions. I had no issues about that at all.
"Someone is always going to take a runner on something like selling shirts. But you could say that about every player we have signed."
