Dinamo Moscow coach Yuri Semin has revealed he will not try to prevent Nuno Maniche leaving the club.
Maniche has been unhappy since he moved to Moscow from Porto earlier this summer and has been linked with several clubs.
“The question of Maniche is still without an answer,” Semin told Sport Express.
“Only players who want to play for Dinamo will stay, like Derlei and Costinha. They are happy to play for Dinamo, they are ready for the battles.
“They both understand what it takes, at first they thought the Russian championship was very easy – in reality it’s very hard – harder than the Portuguese.
“There are not many players who can adapt to play in Russia.”
Manchester United, who are looking for a replacement for departed skipper Roy Keane, are understood to be keen on the Portuguese midfielder.
