The former was in particularly fine form, scoring the first, laying on the second and generally being a menace throughout. And it led one ex-player to hail his importance to the Arsenal team, even though he was not watching the match.
Michael Owen took to Twitter to stress that Arsene Wenger should stick with Oxlade-Chamberlain in the games to come, with his pace a vital factor in the absence of the injured Theo Walcott.
Given that Arsenal have lacked runners at times this season - and with Mesut Ozil struggling as a result - it is no surprise that the young winger is now regarded as a vital component following Walcott's long-term absence.

Not watching the match but surely Wenger must stick with The Ox. Without him Arsenal lack pace in the absence of Walcott.— michael owen (@themichaelowen) February 16, 2014
The modern game is about pace people. Doesn't have to come from every player but if nobody in forward positions has it you're in trouble.— michael owen (@themichaelowen) February 16, 2014
