Santos was on loan and benefited him. Yes, Josh is super talented but realistically do you see him playing infront of James and Gusto? Or Fofana, Chalobah, Tosin? Even with injuries can't see a lot of minutes. He can take Colwill route and establish himself on loan. When players are real deal they make their way to the first team no matter the circumstances. Courtois, James, Colwill... And I'm sure in the future Josh, Penders... Santos now.
