It seems like Chelsea's search of a goalkeeper will never end. 

Because this time there are rumours like they are interested in the Brentford goalkeeper David Raya. He has played in 23 games in total so far and conceded 30 goals. 8 of these games were clean sheets for him. This is pretty good to me considering the team he plays for. However Chelsea still have contracts with Mendy and Kepa both for two more years now. I wonder what Potter is thinking about this situation. We don't even know if this is his idea. I don't think Chelsea's main problem is a goalkeeper now. They should focus on weak spots in the team first by creating some strategies for them.
