Arsenal boss Mikel Arteta says managers and referees must work together to help "make the game better".
Arteta was this week found not guilty of misconduct charges levelled by the Football Association after his comments about Newcastle's controversial winner against Arsenal last month.
The 41-year-old said his hearing had been "a really good, well-run process".
He added: "It's not about 'them', it's 'we'. We want to do the game better. We're all in this together."
Arteta had described the video referee assistant's decision to award Anthony Gordon's winning goal at St James' Park "embarrassing" and "a disgrace".
