On May 21, South Korean midfielder Park Ji-sung signed a one-year sponsorship agreement with Asiana Airlines, South Korea's second-largest carrier.

Park, who returned home on May 18 from Britain, declined to comment at the ceremony held at the airline's headquarters.

He was on crutches after undergoing right knee surgery at a hospital in Colorado, the United States, late last month.

Under the contract, Asiana will provide Park and his parents with first-class seats whenever they travel on one of the airline's routes.

Park is now serving for the Manchester United in the English Premier league.
