Porto goalkeeper Diogo Costa remains on Manchester United's radar.
A Bola says United are interested in signing Porto goalkeeper Diogo Costa in the summer.
David de Gea is out of contract at the end of the season, and it remains to be seen if the Reds will extend his deal.
As a result, the club continue to be linked with several shot-stoppers.
It is thought that Costa would cost United 75m, with the goalkeeper having recently put pen to paper on a new contract with a release clause.
