For a brief moment Crystal Palace believed. But then Chelsea threw Eden Hazard and - well - you know the rest.
The game was evenly poised at 1-1 when Maurizio Sarri sent for his mercurial Belgian, who'd missed the previous three games with a back injury, in the 64th minute.
In the 65th minute, Chelsea were back in front - inevitably Hazard was the instigator, his cross sweetly struck home by Alvaro Morata.
