West Ham United are reportedly interested in signing Porto left-back Miguel Layun.
The Mexican international, who is currently on loan at Sevilla, has impressed in Spain after scoring two goals in 16 appearances and it is likely that the 29-year-old will leave Porto at the end of the season.
Sevilla have the option to make Layun's move permanent for €5m (£4.4m), although Portuguese outlet A Bola says that West Ham will swoop for the full-back if he does not stay in Spain.
Layun, a former Watford defender, played four times in the Premier League for the Hornets after they were promoted in 2015 but was sent out on loan to Porto in the same year.
West Ham could look to strengthen in the left-back area, with Patrice Evra's short-term deal at the London Stadium coming to an end.
