Januzaj made his competitive debut for Manchester United against Wigan Athletic on 11 August 2013 in the Community Shield, coming on for Robin van Persie with six minutes left to play. He made his Premier League debut a month later, coming on as a 68th-minute substitute for Ashley Young in a 2–0 home win over Crystal Palace on 14 September. On 5 October 2013, in what was his first start for the club, Januzaj scored twice as United came from behind to claim a 2–1 victory away to Sunderland. In an effort to stave off interest from other clubs, who could have signed Januzaj for "minimal compensation" on the expiry of his existing contract in June 2014, Manchester United signed Januzaj to a new five-year contract on 19 October 2013. On 3 December 2013, he was nominated for the BBC Young Sports Personality of the Year; at the time of his nomination, he had played in ten games for Manchester United.
