Arsenal legend Bob Wilson has slammed journalist Piers Morgan for his constant criticism of Arsene Wenger, labelling the Gunners fan and former chat show host an ‘incredibly pompous individual’, reports the Independent.

Morgan has become well known for his tirades against the Arsenal boss on Twitter.

He was amongst a number of Arsenal fans to react furiously to Wednesday night’s Champions League defeat at home to Monaco.

The 3-1 loss is already being labelled as one of the worst performances since Wenger took over at the club in 1996, and means his side will have to score at least three goals in the return leg if they are to make it to the last eight of the Champions League for the first time in five years.

Wenger has taken plenty of criticism since the result, with Morgan once again calling for the Frenchman to be sacked.

But Gunners legend Wilson has defended Wenger, and launched his own attack on Arsenal’s most outspoken supporter.

“I would like to say this about Piers Morgan," Wilson said.

"He claims to be an Arsenal fan, but if you’re a supporter of a club you have to be through thick, thin, laughter, smiles and tears. He has never been a proper fan.

"I see him on Twitter and he drives me mad. He’s an incredibly pompous individual and he has no understanding of what it is to be the manager of a football club. I can only tell you this about Arsene, and I am biased to a degree, but i’m not stupidly biased. You will not find any manager ever, more dedicated to doing his job than Arsene.

"With him it's always about the man before the player and that’s very rare for a manager. His first concern is about you as an individual rather than you as a player. Always has been and always will be.

"He’s been there for a long time with incredible glory times, league titles, appeared in a Champions League and FA Cup finals. He's changed the club totally.

"Above all that thought he’s a really decent human being, who cares."

Morgan responded with a series of tweets in which he claimed to be 'hurt' by Wilson's comments.

“I love @Arsenal with a passion. Disagree me over players/manager etc. But NEVER doubt my devotion to the Club. That hurts. #afc”
