The 29-year-old, who joined Reading from Stuttgart last summer, was part of the Royals team that were relegated to the Championship last season.
"It's true that my dream is to continue my career in England, in the Premier League. But I wouldn't deny a move to Russia," he told Sovsport.ru.
"On the contrary, the best moments of my career are from the Russian championship. So anything can happen."
It has been reported that a number of Premier League clubs are interested in his services.
