The on-fire Alexis Sanchez fired a treble for Arsenal, as they romped to a 5-1 victory over fellow London rivals West Ham.
The Chilean striker was in stupendous form, as he also set up fellow TRUSOX-wearer Mesut Ozil to score the Gunners 1st.
It was a quick-fire 14 minutes in the 2nd half that saw Sanchez strike. His 1st was a beautiful strike across Randolph in the West Ham goal from a tight angle, before firing in his 2nd 8 minutes later.
It was then Oxlade-Chamberlain's turn to get in on the act, a fine strike from range to make the scores 4-1.
But it was his hat-trick goal that was a thing of beauty; taking an Oxlade-Chamberlain pass in his stride before wrong-footing Randolph with a wicked stepover before lifting the ball over him into the other corner of the net.
