Diego Costa rejoins Chelsea first-team training

Diego Costa rejoined Chelsea's first-team training at Cobham on Tuesday, Sky sources understand.

The striker was alongside his team-mates for the afternoon session

having spent two days training on his own while the rest of the squad enjoyed time off.

Costa did not travel with the senior squad for their 3-0 win over Leicester City on Saturday, with a back injury being the official reason for the forward's absence.

According to Sky sources  Costa was spotted in a training ground row with head coach Antonio Conte against the backdrop of a £30m-a-year offer from Chinese club Tianjin Quanjian, and was due to meet the Chelsea boss on Tuesday.

Tianjin Quanjian's owner has since indicated Costa's hopes of moving to the Chinese Super League have been scuppered by a new restriction on foreign players.
