Aston Villa boss Tim Sherwood believes that Arsene Wenger has done a "tremendous job" at Arsenal in his 19 years at the club.
The Frenchman was under fire after the Gunners went nine years without lifting a major trophy, which was ended last season when his side defeated Hull City in the final of the FA Cup.
Sherwood feels that criticism of Wenger is ridiculous considering his achievements during his tenure with the Gunners.
Sherwood told reporters: "You have got to be careful what you wish for as a fan. For me, he's done a tremendous job. If you line up the chairman and every director in a football club, they all want a Wenger. Maybe Chelsea and Man City might be an exception because they've got gazillions of pounds to keep throwing at it.
"If you want a sustainable business and someone to run it through, I think Arsene Wenger is a great model of that. It does drive me mad if someone has never stepped into that technical area and claims to be the expert. That is a little bit gruelling. They don't know what it's like. It's impossible for them to know.
"When you first step in the technical area it's a whole expectation of the football club. I don't think anyone should be criticising Arsene Wenger. You can criticise Tim Sherwood all you want. I think it's a bit rich criticising Arsene Wenger. I think he's an incredible manager."
Villa and Arsenal face off in the final of the FA Cup at Wembley on Saturday.
