Diogo Dalot believes that rumoured Manchester United transfer target Diogo Costa could be one of the best goalkeepers in the world some day.
Costa, 23, has been tipped to replace David de Gea between the Old Trafford posts, despite the current United No.1 agreeing a new contract amid unrelenting criticism over his recent displays. De Gea is going through arguably his worst run of form since signing for the Red Devils from Atletico Madrid in 2011, having made another clanger during Sunday's woeful 1-0 defeat away to West Ham.
The Spaniard's series of errors has prompted manager Erik ten Hag and his recruitment team to discuss signing a new goalkeeper who could compete for the gloves next season. One of those is understood to be rising Porto star Costa, who's a good friend and international team-mate of United defender Dalot's.
