London attacker Roman Pavlyuchenko plans to leave the club this summer.
After recovering from an injury, the 29-year-old footballer demonstrated good physical form, but remains among the reserves in the capital's team.
"I feel like the coach doesn't trust me, and no matter how well I play, score goals, and try hard in training," the Russian said. "No one makes him change his mind.
"Even when I play and score, I don't get a chance to show myself in other matches. I'm tired of sitting on the bench and waiting for opportunities."
And he added: "That's why I won't extend the contract, which expires at the end of the season, and I will leave the club."
This season in the English championship, in 17 matches, of which 9 started in the starting lineup, the Russian national team player scored 5 goals.
