Man Utd dumped Arsenal out of the FA Cup on Sunday despite being down to 10 men for over an hour, and the humiliation didn't end there for Arteta who was targeted by United's social media account post

Mikel Arteta described Arsenal's FA Cup third-round defeat to Manchester United on Sunday as a one-in-a-thousand occurrence after losing in a dramatic penalty shootout at Emirates Stadium. Bruno Fernandes put the visitors in front on 52 minutes before Diogo Dalot was sent off nine minutes later for a late tackle on Mikel Merino.

Mikel Arteta said his Arsenal team “deserved to win by a mile” as they fell to an “unbelievable” FA Cup defeat at home against Manchester United.
