Newcastle United have been linked with a summer move for Mexican defender Miguel Layun.
United face a three-way battle for the Porto left-back, according to Portuguese publication Record, with Italian giants Roma as well as Espanyol said to be keen to add the 28-year-old to their ranks.
Newcastle boss Rafa Benitez is in the market for defensive reinforcements this summer, with the likes of Eliaquim Mangala of Manchester City and Ryan Shawcross of Stoke City heavily linked.
And while the centre of defence is a more pressing concern for Benitez, there is set to be some movement at full-back, too.
Benitez relied heavily on Paul Dummett, United's most used player in their Championship winning campaign, on the left side last season while splitting responsibilities on the right between Vurnon Anita and DeAndre Yedlin.
With Anita set to depart when his deal ends next month and Jesus Gamez almost certain to be shipped out, as well as the futures of left-sided reserves Massadio Haidara and Achraf Lazaar undecided, the United boss is looking to add depth on the right and left.
Layun, who can play on the left or the right, played 25 games in all competitions for Porto, whose manager Nuno Espirito Santo was recently sacked, last season.
The 50-times capped Mexican international spent 18 months at Watford, starring in their promotion campaign after joining in January 2015.
But he made just three appearances in the Premier League for the Hornets, scoring on debut before being farmed out on loan to Porto, where he was later signed for around £5million.
