The Zenit striker has come in for some stern criticism after his profligacy against Czech Republic and Poland and could make way for either Roman Pavlyuchenko or Pavel Pogrebnyak
The Zenit striker squandered a slew of chances in his country's tournament-opening 4-1 demolition of Czech Republic and also failed to break his duck in the 1-1 draw with Poland.

"I cannot tell you anything about the line-up," the Dutchman stated during a press conference on Friday evening. "Kerzhakov is a player who can score a goal at any time and that is very important for us."
The Russians only need a draw to seal a place in the last eight and Advocaat is confident of picking up at least a point, provided his players improve their ball retention.
"The first half against Poland was very good," the former Netherlands boss mused. "In the second half we played not so good and Poland were stronger.
"We lost the ball too often. But now we must get a good result against Greece."
Russia's final fixture in Group A is scheduled to get under way at 20:45CET.
