Arsenal legend Patrick Vieira believes that Unai Emery needs more time at the club.

The Gunners lost to Leicester City at the weekend, leaving them nine points off a top four position, with many supporters calling for Emery to be sacked.

But Vieira thinks the Spaniard can get it right with time.

"It's true Arsenal are going through a tough spell," he told reporters on Monday.

"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."
