Bayer Leverkusen’s Sidney Sam asks ‘Who the XXXX are Chelsea?’

BAYER LEVERKUSEN star Sidney Sam warmed up for tonight's Champions League showdown with Chelsea by sneering: "Who the f*** are you?"

The German striker posted a picture on Facebook of himself next to a Chelsea shirt, smiling and making a thumbs-down gesture.

And he accompanied his visual taunts by writing in English: "Who the f*** is Chelsea London?"

Sam can expect some fearful stick from irate Blues fans at Stamford Bridge tonight.

And he has effectively written a pre-match team talk for Chelsea chief Andre Villas-Boas.

Sam, born in Kiel to Nigerian parents, has scored 15 goals for Leverkusen since joining them last year in a £2million switch from Hamburg.

He added: "Chelsea are clearly a hard nut for us to crack.

"But we can go over there with a lot of confidence. We don't intend to hide away, and I am feeling fit and ready."
