United are weighing up an offer for Sergio Ramos.
The veteran 34-year-old defender is out of contract at the end of this season but remains in negotiation with Real over a possible extension.
Calciomercato reports United are hoping Sergio Ramos will consider their own contract offer.
United would be prepared to match any Real’s wage offer on a two-year contract.
Ex United boss Louis van Gaal unsuccessfully attempted to lure Ramos back in 2015.
Manchester United are also reportedly ahead of Manchester City in their pursuit of Spain’s record cap holder.
