Nice coach Patrick Vieira says Arsenal need to stand by manager Unai Emery.
Vieira, who was himself a rumoured replacement for Arsene Wenger when Emery took the job 18 months ago, believes that is the right call.
"It's true Arsenal are going through a tough spell," Vieira said. "But I haven't watched all their matches, so I can't talk about their game.
"They have a coach who is qualified and who works well. When a club is having a difficult time, it's important to be united. I think he has enough experience to get them through this difficult spell.
"We have to get behind him and give him time to change things. I am not sure a change of manager will fix the problems."
