Alexis Sanchez scored twice in four second half minutes to give Arsenal manager Arsene Wenger victory on the night he equalled Alex Ferguson's Premier League record of matches in charge with a 3-2 win over Crystal Palace. Sanchez's brace -- the second a beauty from Jack Wilshere's superb pass -- added to Shkodran Mustafi's first ever away goal for the Gunners was just enough to get them past the Eagles in Wenger's 810th Premier League game as a manager. James Tomkins’s 89th minute header -- Andros Townsend had drawn them level at 1-1 early in the second-half before Sanchez's scoring burst -- ensured a nervy finish, but the Gunners deserved to run out winners and end Palace’s eight-game unbeaten run. Arsenal drew level with fourth-placed north London rivals Tottenham Hotspur but with a worse goal difference.
