Arsenal hero Emmanuel Petit has questioned Unai Emery's impact this season.

Petit says Emery needs to completely rebuild the squad because it is not good enough defensively, lacks team spirit and they even got “lucky" during their unbeaten run earlier in the season.

He said: “It's like Wenger is out but I have the feeling that it's the same old story. What's happening after Arsene Wenger's era, I think we were expecting more from the club.

“I am disappointed.

“You are telling me that Emery has the same problems that Wenger had.

“Nothing has changed. So why did they sack Arsene? If you sack the manager, you need to start a revolution. But I ask the question: why did they sack Arsene? If someone can give me the answer then I'll be very happy.

“If you don't give the control to Emery, allow him to oversee a revolution, give him the power to bring in new players to help him change the style on the pitch, then why create all of this mess?

“This team is not good enough to fight for the title. This team is strong enough to fight for third or fourth place and that's it. They've been like that for years and years. You don't have to be a magician to understand that.

“I was thinking, 'OK, you sacked Arsene Wenger for good reasons.' But then I was expecting a revolution at the club. But it's not happened. You sack Arsene, but then you have to give the power to Emery to change things. But, honestly, nothing has happened. It's just the same now as it ever was."
