Eden Hazard was in sparkling form as Chelsea restored their seven-point lead at the top of the Premier League table with a 3-1 win over Bournemouth.

Adam Smith’s own-goal opened the scoring in an action-packed first half, a sliced Diego Costa shot hitting his face before going in, and three minutes later Chelsea had doubled their lead.

While the first was scruffy, the second goal was anything but. N'Golo Kante set Hazard through on goal with a delicious through ball, then the Belgian calmly rounded Artur Boruc with a lovely feint and rolled the ball home.

Bournemouth were second best but did offer something going forward and got a goal back shortly before half-time through the in-form Josh King, whose deflected effort beat Thibaut Courtois at his near post.

Costa, who is still looking for Premier League goal number 50, twice failed to make contact with inviting crosses after the break but did win the free-kick that secured the win for Chelsea. Marcos Alonso stepped up and curled it expertly into the top corner in the 68th minute.
