Premier League Leeds United avoided an FA Cup upset by producing a second-half comeback to defeat Championship side Derby County and reach the fourth round.

James Justin scored his first goal for Leeds United since joining from Leicester City in the summer, in a second-half comeback after Derby County took the lead thanks to a Ben Brereton Diaz strike.

Among them, new midfield signing Oscar Fraulo is given his debut, while captain Lewis Travis makes his first start since returning from injury.
