Koroma's performances did not go unnoticed as Huddersfield Town were quick to snap him up last summer for an undisclosed fee. He has only made nine appearances for the Terriers during his first season, but new manager Danny Cowley has been impressed by what he has seen of him. Cowley, and his brother Nicky, tried to sign Koroma when they were at Lincoln but they are glad to have him now. In an interview with the Huddersfield Examiner in October 2019, Cowley said: "Josh is a talented boy and there are not many 20-year-olds in the whole country whose stats match to his in terms of appearances and the amount of football he has played - and also his goals per game ratio. He is a good kid, we like his attitude and we just want him to get a bit fitter. He has got a really good chance"
