(Video) West Ham 1-5 Arsenal: Stunning Alexis Sanchez hat-trick leads Gunners to crucial win

Arsenal secured a 5-1 win over West Ham United at the London Stadium on Saturday, closing the gap to Premier League leaders Chelsea to three points.

Mesut Ozil opened the scoring for the Gunners thanks to a brilliant bit of unselfish play from Alexis Sanchez, but the Chilean international wasn’t done there.

After extending their lead with a brilliant solo goal, Sanchez made it 3-0 with an unstoppable driven shot into the corner as he seemingly killed the game off.

Andy Carroll grabbed a consolation goal and fans would have been forgiven for assuming that it would be the end of the scoring as Arsenal looked to close things out and seal all three points.

However, Alex Oxlade-Chamberlain decided it was his turn to produce a stunning goal of his own after curling an effort beyond Darren Randolph to put the icing on the cake.

The England international was disappointing for the most part, but he was at least able to add a goal to his evening’s work as Arsene Wenger saw his side move back to within three points of leaders Chelsea.

Sanchez added a fifth with a brilliant effort late on as he kept his composure and showed his class to leave Randolph stranded with a wonderful chipped finish to compound West Ham’s misery.

After their disappointing EFL Cup exit in midweek, it was the perfect response led by an exceptional hat-trick from Sanchez who proved yet again he is ready to lead the line and fire the Gunners to silverware this season.
