Unai Emery has come under fire for failing to shake Mikel Arteta's hand after Arsenal's 4-1 pummeling of Aston Villa.
The Gunners struck four times in the second half on Wednesday night to claim a statement win at the Emirates, delivering a hammer blow to a Villa side who were subject to growing talk of a Premier League title challenge.
Arteta, who replaced Emery as Arsenal manager in December 2019, was clearly elated and immediately celebrated with his coaching staff on the touchline after the final whistle.
