On 1 March 2008, Park scored his first league goal of the 2007–08 season after returning from his long-term injury against Fulham. His lack of appearances had caused much controversy in South Korea, but he proved his worth when he delivered an assist to Wayne Rooney in the Champions League quarter-final match against Roma. On 29 April 2008, Manchester United advanced to the Champions League Final after beating Barcelona. Park, however, was excluded from the squad to face Chelsea in the final despite starting both legs of the semi-final; manager Sir Alex Ferguson later stated that leaving him out was one of the hardest decisions he had had to make throughout his managerial career.
