Chelsea have reportedly made contact to sign Porto goalkeeper Diogo Costa who is also wanted by Manchester United ahead of the January transfer window.
The Blues could be forced to dip into the transfer market for a new shot stopper after recent speculation has hinted that Edouard Mendy is considering leaving the club due to his limited first team opportunities.
An exit from the Bridge for the Senegalese goalie will open the door for a fresh face, potentially in the shape of Diogo Costa, with the 23-year-old forcing his way into the international reckoning with the Portugal team in the ongoing World Cup.
According to a report from the Spanish news outlet Relevo, it is claimed that Chelsea have initiated talks to sign the Porto man super-agent Jorge Mendes conveying his interest in brokering a blockbuster transfer next summer.
Mendes is confident of Costa sealing a move to the Premier League where his suitors include the likes of Chelsea and Manchester United with both clubs willing to fork out a big fee to secure the transfer.
