Krasic also confirmed reports that he wants to quit CSKA Moscow.
Manchester United and Portsmouth are both interested in the 23-year-old.
“I think that the time has come for me to leave CSKA after several seasons which have been a fantastic success,” he told Serbian newspaper Vecernje Novosti.
“The club are aware of my wish to move, although money is not a problem for them.
“Anyway I have personal ambitions and my wish is to play in England, I know that they [several English clubs] have been following me for a while.
“I am waiting until the end of the [Russian] season in November, when I hope to win a Champions League place with CSKA and after that we will have discussions.
“I know that offers will be sent next month.”
