Arsenal legend Martin Keown has hit out at Brighton coach Roberto De Zerbi's touchline antics.

The Italian has become synonymous with his expressive behavior during games.

De Zerbi was passionately celebrating as his side beat Arsenal 3-0 at the Emirates Stadium on Sunday in the Premier League.

"I honestly feel if Arteta did that down the side of the pitch we'd never hear the end of it," Keown told talkSPORT on Monday morning.

"But it's okay for De Zerbi to do it? I like that kind of emotion.

"I would say, because it's Brighton who are inoffensive, because it's everyone's second-favourite team, we turn a blind eye to it.

“But if that's the Arsenal manager doing that all of a sudden, it's a problem."
