Manchester United are in pole position to sign Porto goalkeeper Diogo Costa, according to A Bola.

The Red Devils are aiming to strengthen the goalkeeping department with David de Gea struggling for consistency.
De Gea is likely to pen a new deal but United are still planning to pursue a marquee option for the number one role.
Costa has been on their radar for a while and A Bola claim that he is on course to move to the Premier League this summer.
It is added that United are leading the pursuit of the 23-year-old but he won’t come on the cheap for the Red Devils.
Costa signed a new deal earlier this season with a €75m release clause and Porto are set to hold out for the same figure.
United were initially content with De Gea as the first-choice keeper but the scenario has changed amid his recent howlers.
Costa would be a fantastic signing for manager Erik ten Hag.
