Chelsea manager labeled Arsenal boss Arsene Wenger a failure specialist last season in words that are coming back to haunt him.
Last season, Jose Mourinho attempted to shine the spotlight on Arsene Wenger's mainstay status at Arsenal despite failing to deliver silverware since 2005.
In contrast, before last term reached it's conclusion, the Chelsea boss had collected a Premier League crown and a League Cup with Chelsea, two Scudetto, a Coppa Italia and a Champions League with Inter and La Liga and a Copa del Rey with Real Madrid in the same time-span since Wenger had lifted the FA Cup nine years ago.
His words… that Wenger was a "specialist in failure" came back to haunt him at the end of the season as, in the same year both he and Chelsea failed to win a trophy, Arsenal paraded the FA Cup around North London.
Jon Snow, during an interview for the World Food Programme, revisited Mourinho's failure-specialist comments, to which the Portuguese notoriously scoffed.
Only a matter of months later and Arsenal once again lifted a trophy, one of far lesser significance, but a 3-0 victory over the reigning Premier League champions Manchester City saw the Gunners triumph in the Community Shield.
Renowned pundit Richard Keys has now asked the question if Mourinho repeats a trophy-less season, whether it will be he who is the expert in failure and whether owner Roman Abramovich will lose patience with the 51-year-old for a second time around.
"[I like Arsenal's] attitude," Keys blogged. "I fancied them for a challenge last season. I had them to finish second but injuries - notably to Aaron Ramsey and Theo Walcott - cost them and they fell away. If they can keep everybody fit this season they'll go close - really close.
"I dont have them down to win the Premier League though," he noted. "I said Chelsea last season and I consoled myself with the view that I was just a season ahead of those who've jumped on the bandwagon now!
"The main reason I went for them last time was Mourinho. It's that simple. He'd been the course and if anyone could get the best out of a lightweight squad he could. He went close.
"I knew he'd get rid of Juan Mata and David Luiz. I got quite a bit of stick for saying that. But I was right. He'll get rid of a few more too if he gets his way.
"That's the point though, in order to do that he'll have to win it. If he doesn't, and he finishes empty handed again, I think he'll be gone at the end of the season.
"Maybe he's just becoming an 'expert' in failure!"
Arsenal may have gotten their season off to a positive start, having avenged a 6-3 defeat to City last season by dominating them yesterday, Sunday.
However, that matters little if they cannot sustained the same performance level when the 2014-15 Premier League season begins this weekend - and it could reach it's hottest point mid-Autumn, when Chelsea host Arsenal at Stamford Bridge on Sunday, October 5.
