On 2 May 2009, Park verbally agreed to a new four-year £50,000-a-week deal at Manchester United, stating, "I have no reason to move. I play at the best club in the world." Following this announcement, Park scored his second league goal of the season – and third overall – in a 2–0 away win against Middlesbrough. On 5 May 2009, Park scored his first Champions League goal for Manchester United in the second leg of the semi-final against Arsenal at the Emirates. He pounced on a slip by Kieran Gibbs and placed the ball over Manuel Almunia in the eighth minute, with the game ending 3–1 (4–1 on aggregate), advancing United to the Champions League final for the second year running. Park became the first Asian player in history to play in a Champions League final, although his team lost 2–0 to Barcelona.
