Sporting Lisbon want a Nani loan deal to be included in the Marcos Rojo transfer
The Red Devils are also keeping tabs on this Argentina international in a bid to improve their currently shaky defence.
An offer of around £17m has already been rejected by Sporting for Rojo, who want their former player Nani to be included in the deal.
The Sunday Times reports that the high wages of the Portugal international make a full transfer unlikely, but a loan move is still possible.
