Former Man United, West Ham and Aston Villa scout Mick Brown confirmed to Football Insider that United and Liverpool are tracking the full-back.
“After his form so far this season, I’ve heard there are a few clubs keeping tabs on him," Brown said.
“Some of the top clubs in the Premier League have been watching him for a while, but the way he’s playing at the moment, that interest has grown.
“He’s one of the leading candidates for any team looking to sign a left-back. I’d count Man United and Liverpool among them. Whether they’ll make a move or not, I’m not sure, but they’re among the clubs tracking him.
“From what I hear, Fulham won’t let him leave in January anyway, so if it happens it won’t be until the end of the season.”
