Former Arsenal striker Ian Wright claims he can't understand the 'obsession' Jose Mourinho has with Gunners boss Arsene Wenger.
The pair have constantly been at loggerheads over the years and the fierce rivalry escalated last season when the 'special one' claimed Wenger was a 'specialist in failure'.
After Mourinho was criticised by media and pundits alike following Chelsea's recent form, he responded by insinuating that Wenger is the only manager that's never under pressure.
Wright admits that the media's respect for the 65-year old Frenchman could be what gets under Mourinho's skin.
"His obsession with Arsene Wenger is mystifying. I just can't understand it," the 51-year old told the Sun. "There's something that happens with him whenever he talks or thinks about Arsene. He gets antagonized all the time.
"I think the big problem is that Jose looks at Arsene and his treatment from the media.
"Jose rightly feels Arsene hasn't achieved as much as he has. I think his issue is that Arsene has not won as much or achieved as much as he has – yet still gets as many plaudits. It just irks him that Arsene doesn't get more criticism.
"What I can't understand is why it irks him so much when he's got the medals to show everybody what he's about. He just can't be happy with himself, for some reason, even though what he does is brilliant," he concluded.
