The retired French midfielder, who played for both of the Premier League giants, was the victim of verbal abuse from a supporter, as reported by talkSPORT's commentary team.
Explaining what was going on, Sam Matterface said: "There's a supporter who was bellowing in his face at this moment in time.
"It's a bit unnecessary from him getting involved with Nasri who's just trying to do his job [punditry].
"Nasri is just standing there being barracked by the supporter, there should be more stewards around here making sure it doesn't happen."
Former Gunner Perry Groves added: "This is where the press set-up is not the best. The security have to get the fan out.

Ending his career with Anderlecht in 2020, Nasri was returning to the Emirates on media duties.
