Mikel Arteta has drawn Aston Villa fans' ire after they spotted him appearing to put off Jadon Sancho by leaving his technical area when the winger had the ball during Arsenal's win over Unai Emery's side.
The hosts ran out the 4-1 winners at the Emirates in what was eventually a routine win for the Premier League title chasers.
But there was no shortage of needle between the two sides on Tuesday evening, with Villa manager Emery snubbing Arteta's handshake after the final whistle, and travelling goalkeeper Emi Martinez swept up in a furious row with Arsenal supporters as he disappeared down the tunnel.
