Jose Mourinho says it is "no coincidence" that Chelsea have struggled to win trophies since they sacked him as manager in 2007.
The Blues have added just one FA Cup to their trophy cabinet since Mourinho was shown the exit door at Stamford Bridge and it has come as little surprise to the self-proclaimed 'Special One'.
The Portuguese coach is now in charge of Inter Milan, who Chelsea face in the last 16 of the Champions League, and he believes it has been proven that it was a mistake by Roman Abramovic to let him go.
He said in Nuts: "Chelsea have suffered in the last two years, and it's no coincidence that their decline happened after I left.
"We had a unique relationship as a manager, players and fans, and when you break that, it's not easy to fix.
"They've had a lot of coaches since and maybe some didn't have the mentality for the club. Maybe they tried to change too much of what we put in place.
"I knew there was no time for a long-term plan with the owner they have at Stamford Bridge. You must win the title in your first season or say bye-bye. I gave them what they needed but I always knew it wasn't a job that would last forever.
"Maybe they would've been better off sticking with me than changing manager when they did."
