Israel midfielder Benayoun has been the target of boos and jeers from elements of the Blues’ support in recent months, some of which are reported to have “crossed the limit”, according to the player.
Chelsea confirmed to Eurosport that the club are looking into reports of abuse against the player, but would not say whether it was of an anti-Semitic nature, as has been widely reported in the British media.
The player himself took to Twitter to complain of the abuse, and while he said it was "crossing the limit" he did not expand on its exact nature.
“The booing came from (a) small part of the Chelsea fans... doing it since I did an interview about (Fernando) Torres,” Benayoun said, referring to quotes in a recent article that supported the Spanish striker and blamed his struggles on mismanagement at Chelsea.
“There is some other issues the club is taking care (of) and try to handle them in the right way... as sometimes people are crossing the limit. And I’m sure the club will sort it.”
Benayoun, 32, was loudly jeered by travelling fans when he came off the bench on Sunday against former club Liverpool. That abuse did not appear to be anti-Semitic, but the player is understood to have informed the club of previous incidents with a more sinister element.
In addition to opposing his support for Torres, some fans were outraged when he kissed the Arsenal badge during a loan spell last season, with others believing he does not warrant a place in the team.
Benayoun joined Chelsea from Liverpool in 2010 but has struggled to command a first-team place and spent time on loan at both Arsenal and West Ham. He has since found himself back in the picture under Rafael Benitez, who managed him at Anfield.
It is not the first time Benayoun has been involved in allegations of anti-Semitic abuse, having criticised elements of West Ham’s support for chants made during a match against Tottenham this season.
Chelsea have also been tainted by several racial incidents, with captain John Terry banned for four matches for racially abusing QPR’s Anton Ferdinand last season, while referee Mark Clattenburg was mistakenly accused of using “inappropriate language” towards John Obi Mikel earlier this campaign.
