Russia coach Guus Hiddink has told Roman Pavlyuchenko to find himself a new club if can't get regular game-time with Tottenham.
The 27-year-old broke down in training on Thursday with a thigh injury and is a doubt for the clash at the Luzhniki Stadium on Saturday, a match which Russia must win to have a realistic chance of qualifying automatically for next summers finals.
Although Pavlyuchenko later said the injury was not serious, Hiddink confided that his No 9's body appeared had been weakened by a lack of match practice at Spurs.
"Roman pulled a muscle," said Hiddink. "We need to see how it reacts in training on Friday. 'I'm concerned. Pavlyuchenko has no match practice at Tottenham and his body seems to be unaccustomed to intense stress.
"I can't say that we had an intense workout, but I've connected the nature of his injury with a lack of match practice for Roman. You can't say he is immune from the same stresses in the match against Germany.
"The fact that he doesn't play, and wasn't even in the squad for the last match, disturbs both us and him."
