Atletico Madrid midfielder Saul Niguez is reportedly still a transfer target for Manchester United.
Injuries to Scott McTominay and Paul Pogba have left the Red Devils extremely short in the middle of the park, leading to suggestions that the club could enter the winter market for a new midfielder.
Ajax's Donny van de Beek has recently been linked with a move to Old Trafford, but according to the Daily Record, Saul is also being considered by the 20-time English champions.
The 25-year-old continues to be linked with a move away from Atletico despite signing a nine-year contract with the Spanish giants in the summer of 2017.
The Spain international is closing in on 300 appearances for Diego Simeone's side in all competitions, while he has featured on 25 occasions during the current campaign.
Rumours of a potential swoop for Sporting Lisbon attacker Bruno Fernandes have also resurfaced, with United's squad currently stretched.
