The Serbia international was again outstanding for CSKA in midweek Champions League action against Wolfsburg and scored a spectacular goal.
Krasic has admitted he has ambitions of playing for United, while he has also been linked with Inter and AC Milan in recent days.
And the midfielder's agent, Dejan Joksimovic, told calciomercato.it: "On Inter I do not know anything. Milan I heard from a month ago, through my partner Naletilic, but nothing concrete.
"At the moment, I think that if he leaves CSKA in January, he will 90 per cent go to England.
"Manchester United? In the Premier League, he's followed by three or four big clubs (Arsenal, Manchester City and Chelsea in addition to United), which have major economic resources. The price certainly is not less than 15 million euros."
Joksimovic says a move to Italy could be on if Krasic remains in Russia beyond the January transfer window.
He said: "If he does not leave in January, then the topic of Italy could return in the summer. Milan in January has taken David Beckham and the last non-EU place was taken by Dominic Adiyiah.
"Again, in January, it is much more feasible to see him on the English track, also because there is not the problem of work permits."
