Conte sounded very sure yesterday about Costa.
‘Diego is our player. He is a fantastic player, a player with a fundamental importance and there is no problem. He stays with us, he is working very hard, he is very happy to work with his teammates and with me in the new idea of football. He is a Chelsea player.
‘He is an important player, a very strong player, one of the best in the world, and I am sure when he goes into our ideas he will score a lot of goals for us.’
