Raheem Sterling inspired Chelsea to an impressive comeback win as Burnley slumped to their fifth successive Premier League home defeat of the campaign.
Eighteen-year-old French forward Wilson Odobert marked his first Premier League start by drilling low and hard past Robert Sanchez to send home fans into raptures at Turf Moor.
Chelsea were disjointed for spells but were back on level terms before half-time thanks to an unfortunate own goal.
A cross by Sterling, back in the starting XI after a virus, struck the knee of Belgium defender Ameen Al-Dakhil and looped over James Trafford into the net.
Chelsea then scored three times in a strong second-half showing to take the points.
