Zenit striker Alexander Kerzhakov is considering his options at the club, according to Russian newspaper Izvestia.
The Russia international is no longer considered an indispensable member of the starting line-up, with boss Luciano Spalletti warming up to the idea of playing Hulk as a centre forward.
Kerzhakov was one of several Zenit players who voiced their discontent following the arrival of Hulk and Axel Witsel in the summer transfer window, and it appears his relationship with the Italian coach is at an all time low.
He is, therefore, thinking about leaving the club in the summer transfer window, and there is every chance he will hand in a transfer request, that is unless Luciano Spalletti gets the boot at the end of the current campaign.
Alexander Kerzhakov, 30, returned to Zenit in January 2010 and has since scored 46 goals in 76 Russian Premier League fixtures.
He remains an important member of the Russia national team, and has scored 3 goals in 4 2014 World Cup qualifiers.
