The Russian job-share is beginning to get to Chelsea boss Guus Hiddink.
The Dutchman, in charge of both Russia and Chelsea, made a cock-up speaking ahead of Saturday's Azerbaijan clash.
He said: "Andrey (Arshavin) is strong physically and psychologically. He likes it in England. And he's already become one of Chelsea's leaders."
After realising his mistake, he added: "What a slip of the tongue. Of course he's a leader in Arsenal - but he would be doing the same at Chelsea!"
