Wolves are determined to keep hold of Ruben Neves.
The Birmingham Mail says Molineux chiefs are unlikely to be persuaded to let their star man go.

United this summer parted with Michael Carrick after 12 years at the club, while City said goodbye to Yaya Toure - the Ivorian leaving after his eighth season at the Etihad.
