Diego Costa has demanded a pay rise from Chelsea or will seek a move away from the club, according to reports.

Costa is believed to have been involved in a bust-up with Chelsea coaching staff last week, and then missed the club's 3-0 win over Leicester. Chelsea said Costa was suffering with a bad back.

The Spaniard is back training with the first team after recovering from the injury and could feature against Hull on Sunday.

But, according to The Sun, Costa has told Chelsea he wants his wage, said to be £150,000 ($185,000) per week, to be increased if he is to stay.

The 28-year-old is the joint top-scorer in the Premier League this season, along with Arsenal's Alexis Sanchez, on 14 goals.
