Diogo Costa's superb display against Slovenia last Monday attracted the attention of several European giants and some are already thinking about counting on the keeper for next season, as is the case with Chelsea.
The English club is looking for a goalkeeper to replace Robert Sanchez, who has been rumored to be on the way out of the transfer market, and Diogo Costa's name has come up at the right time.
Coach Enzo Maresca, according to the Standard newspaper, "has his eye on" Diogo Costa, although the Blues know that the player could cost 75 million euros.
Diogo Costa, it should be remembered, has a contract with FC Porto until June 2027 and is valued at 40 million euros, according to Transfermarket.
