Conte is planning to reintegrate Costa into his squad, although it is unclear how long that process will take

Diego Costa rejected the offer of a new contract at Chelsea before last week’s bust-up with manager Antonio Conte.

Chelsea are believed to have offered Costa a five-year deal worth £200,000 a week — a £50,000 weekly increase on his existing wages — but the striker was unwilling to commit himself to the club.

The Spaniard has since received a staggering counter-offer from Chinese side Tianjin Quanjian worth £570,000 a week, which Chelsea officials fear has turned his head. Conte claimed that Costa’s absence from Chelsea’s 3-0 win over Leicester City on Saturday evening was solely because of a back injury, although other sources are convinced that his reluctance to train is connected to the offer he has received from China.
