Park Ji-sung is set to sign a lucrative new Manchester United contract during the early weeks of the season, reports the Daily Mail. The South Korean's present deal expires next summer, but the 28-year-old has already proved his worth in four successful years at Old Trafford following a £2million move from PSV Eindhoven.

"We are looking to extend Park's contract because Alex is very happy with him," said United chief executive David Gill.

"When we signed Ji-sung Park it was for footballing reasons. But, without a doubt, it has had an impact on our commercial activity in South Korea.

"We have one million credit and debit cards here, which is phenomenal and the enthusiasm of the fans is second to none."
