He is enjoying himself on loan with Cologne, who are currently 11th in the Bundesliga, having scored another two goals last week.
He has now revealed that he wants to make the loan move permanent and stay in Germany.
“I would like to stay at the club,” Tosic said. “The most important thing for any player is regular first-team football and I like Cologne, but I know any decision on my future will only be made in the summer.”
Reports suggest £4.5million would be enough for United, although meaning a loss for United. Tosic joined United in a £16m deal which included Adem Ljajić, although it is believed Tosic cost us £6m.
