Rafa Benitez believes Chelsea fans weren't willing to let the success he had previously had at Liverpool go whilst he was in charge of the Stamford Bridge outfit, reports The Express.
Benitez, who led the Blues to a third placed finish and also achieved Europa League success last season, constantly came in for criticism throughout his short stint at the Bridge.
The Spanish manager, who is now adored at Italian outfit Napoli, believes the Blues' rivalry with Liverpool was ultimately what worked against him at the club.
And when speaking to Spanish paper Marca, Benitez said: "They remembered the successes we had with Liverpool against them, against that powerful Chelsea, and maybe that was stuck in their head.
"That was past. We could not change."
However the former Reds boss insisted that he enjoyed his time at Chelsea, but knew he could never win over a group of fans at the Bridge.
Benitez continued by saying: "With the players and staff I worked with there was a very good relationship but there was a group of fans that could not change the opinion.
Since Benitez's departure at Stamford Bridge, Jose Mourinho has returned to the club with the Blues currently fourth in the Premier League table.
