Sunday 4 December 2016 00:40, UK
Alexis Sanchez fired Arsenal up to second with a stunning hat-trick in a thumping 5-1 victory over West Ham at the London Stadium.
The Chile striker made it five goals in his last two appearances to keep Arsene Wenger's side hot on the tail of Premier League leaders Chelsea, who they trail by three points.
Sanchez also unselfishly set up the first-half opener for Mesut Ozil before striking three times in 15 second-half minutes after the interval.
Andy Carroll grabbed a consolation on his return from injury but the struggling Hammers promptly conceded a fourth to Alex Oxlade-Chamberlain before Sanchez wrapped up a commanding win.
The result sees the Gunners extend their unbeaten run in the Premier League to 13 games while West Ham remain teetering above the relegation zone, a point clear of 18th-place Sunderland.
