Manchester United and Liverpool are keeping tabs on Nicolas Gaitan's situation at Benfica.
A Bola says United and Liverpool are tracking Gaitan's situation, with the winger failing to get off the bench on the weekend against Academica.
Benfica need to sell again in January to balance the books and Gaitan is a prime candidate to be moved on.
The Argentine's contract carries a €40 million buyout clause, but given Benfica's need to sell, he will be available for around a quarter of that price in January.
