Chelsea boss Antonio Conte has hailed Diego Costa as one of the world's best strikers following his match-winning goal against Middlesbrough on Sunday.
The Spain international, who struggled for goals last season, scored his 10th league goal in the 1-0 win over Boro to take the Blues top of the Premier League.
With 17 goals in their last six games – which includes six clean sheets – Conte has got his new side in full flow as the December period awaits, and he admits Costa has played a major role in their impressive performances.
"For me, it's important to have this type of question because in the past, you asked me about his behaviour, about his reaction, about his patience," the Italian told Sky Sports News.
"Now I think he is one of the best strikers in the world and he has to continue in this way, showing his patience, but in the right way.
"He is very focused on the team, to help the team with the ball, without the ball and he is scoring a lot of goals. He has to continue so."
