Jose Mourinho and Arsene Wenger will be arguing into their 90s.
The pair’s feud stretches back to Mourinho’s first spell at Chelsea.
“Wenger has a real problem with us and I think he is what you call in England a voyeur,” Mourinho said in 2005 after Wenger questioned Chelsea’s tactics.
The relationship had begun.
Since then, the pair have collided on more occasions than a bumper car.
Mourinho labelled Wenger a “specialist in failure” in 2014, and the Manchester United boss had another dig at the Frenchman prior to Saturday’s match against Arsenal.
“My last Premier League title was 18 months ago, not 18 years ago,” he said, referencing Arsenal’s last title success in 2004. “It was 18 months ago but I don’t think that I get that respect.”
Mourinho criticised Wenger after the 1-1 draw
Wenger’s lack of success in the past decade - since reaching the final of the Champions League in 2006, the Gunners have just two FA Cup wins to speak of - seems to grate Mourinho to the point that he seems obsessed with the 67-year-old.
In an interview with ESPN Brasil after Saturday’s 1-1 draw, the former Chelsea manager couldn’t resist criticising Wenger some more.
This wasn’t even a thinly-veiled dig. Mourinho believes his rival has “failed to build a team to be champions”.
“I said yesterday at the press conference,” Mourinho said on Saturday. “The Arsenal manager hasn’t won a championship in 14 years. I haven’t won a championship in 18 months.”
“He, in 14 years, failed to build a team to be champions. I’ve been here for four months. And the demand is only for me and not for others.”
One way to shut Mourinho up
Despite Wenger’s team currently sitting six points ahead of United, it’s clear that there will be only one way to shut Mourinho up.
Arsenal can finish in the top four all they like, but until they actually win the title then they have nothing to celebrate.
So, although Mourinho could probably do with refocusing his attentions away from Arsenal and onto his own struggling side, he’s got a point.
Carragher: Wenger's excuses have gone
Jamie Carragher made the point in his column for the Daily Mail on Saturday.
“Had Wenger been appointed in 2006 as opposed to 1996, would he still be in charge of Arsenal, having failed to deliver the Premier League in the last decade?,” Carragher asked.
“Wenger is great for football, his teams are wonderful to watch when they are at their best, but let's not kid ourselves. He worked wonders on a tight budget, keeping Arsenal in the top four just after they left Highbury but the excuses for not winning the biggest prizes have gone.”
