Chelsea upped the pressure on the sides vying for the top four with victory over West Ham as Eden Hazard may have added a few million to his asking price.

The London derby didn't catch light until his wonder goal opened the scoring after 24 minutes at Stamford Bridge.

The 28-year-old, heavily linked with Real Madrid, glided past four Hammers defenders before slotting calmly into the net.

His composed second in time added on iced the cake and sealed a deserved three points for the Blues.

The win lifts Maurizio Sarri's men up to third, above Tottenham in the table.

Spurs do have a game in hand but Chelsea will be confident of returning to the Champions League after a year away.
