Chelsea substitute Ross Barkley headed in a stoppage-time winner to secure a 2-1 victory over Watford.
Kai Havertz put the hosts in front on 11 minutes, tapping in from Kenedy's cross.
Chelsea almost had a second on the stroke of half-time, but Havertz's effort struck the crossbar.
Watford equalised with three minutes remaining when substitutes Adam Masina and Dan Gosling combined for the latter to head in.
However, Reece James crossed for Barkley to nod in his first of the season late on.
Chelsea finish the season in third with 74 points, while Watford end the campaign in 19th on 23 points.
