Reports on Sunday suggested big-spending City were lining up a £20 million bid for the highly-rated youngster as Mark Hughes looks set to bolster his squad during the January transfer window.
Hughes splashed out around £40 million to sign Kolo Toure and Joleon Lescott during the close-season, and it appears the 20-year-old could be next on the Blues’ wish-list.
“They could easily make us this offer if they would like to,” he said.
“But we are staying firm to our vow – Neven Subotic is not for sale.”
And the Serbian – who has featured in every one of Dortmund’s league outings so far this term – admits he is determined to honour his contract and remain in the Bundesliga.
“It is a big honour if such a big club is attempting to sign me, but I am under contract until June 2014 at Borussia Dortmund and still want to achieve many things with this club,” he told Bild.
