Carvalho limped out of their victory over Newcastle United on Monday afternoon after twice falling heavily on his back.

The Portuguese international underwent intensive treatment on the injury on Tuesday and is desperate to be fit in time to face Wanderers at Stamford Bridge on Sunday.

Chelsea know that a result which betters Manchester United's on the final day of the season will earn them the title.

Carvalho has become a vital member of the team and has not been on the losing side in the last 42 league matches he has played in - a run that stretches back to Chelsea's away defeat at Tottenham Hotspur in November 2006.

Striker Salomon Kalou is also struggling with an ankle injury but he should be fit in time.
