Chelsea striker Diego Costa is full of praise for manager Jose Mourinho.

Costa, who impressed during his debut season at Stamford Bridge with 20 Premier League goals, praised the work ethic of manager Mourinho.

"Mourinho dedicates himself completely to his work," he told Bugun.

"He adores his job and immerses himself in it. At the moment the team is resting but I am sure he isn't – he will be planning, doing things to improve the team. Mourinho makes things easier for the players."
