Courtois is a world class goalkeeper that is lacking confidence at the moment. If De Gea is sold this summer, a scenario that i find highly unlikely, Courtois would be the best replacement we could possibly ask for. He was brilliant for Atletico and Chelsea over many seasons, but most football fans have extremely limited long term memory. Just look at the bags of cash being thrown at goalkeepers like Kepa and Alisson, and Courtois is comfortably better than both. Even Oblak, that is at the same level of Courtois, would probably cost us 100 mill.
