Wenger gave Wilshere a place in Arsenal's first-team squad for the 2008–09 season, and he was given the number 19 shirt. He made his competitive debut in a Premier League match against Blackburn Rovers at Ewood Park in September 2008, as an 84th-minute substitute for Robin van Persie. At the age of 16 years and 256 days he was Arsenal's youngest-ever league debutant, a record previously held by Cesc Fàbregas. Ten days later, on 23 September, Wilshere scored his first competitive Arsenal goal in a 6–0 victory against Sheffield United in the League Cup. On 25 November 2008, Wilshere came on as a substitute in a UEFA Champions League match against Dynamo Kyiv, becoming the fifth sixteen-year-old to ever play in the competition. In January 2009 he signed his first professional contract, extending it in July the same year.
