Chelsea manager Antonio Conte says he is unsure when Diego Costa will return from injury after leaving him out for Saturday’s 3-0 win at Leicester.

Costa had a dispute with a coach over his fitness and Conte said the 28-year-old Spain striker complained of a back problem on Tuesday.

There were also reports he is the subject of an offer to move to China.
