LONDON -- Antonio Conte insists that Diego Costa remains valuable to Chelsea even when he is not scoring regularly, and says he has no concerns about the Spain international's performances in recent weeks.
Costa has scored just four goals in 12 appearances for Chelsea since mid-January, when he was dropped by Conte following a training-ground row with a fitness coach over a back injury as well as a lucrative offer from Chinese Super League club Tianjin Quanjian.
