Callum Hudson-Odoi fired a confidence-boosting first Chelsea goal in four months as the Blues saw off Nottingham Forest 2-0 at Stamford Bridge.
The 19-year-old England forward drilled home the opener then had a hand in Ross Barkley's facile finish as Frank Lampard's side coasted into the fourth round of the FA Cup.
Forest had a penalty chalked off after a Video Assistant Referee review, and Ryan Yates' header ruled out for offside.
But this still remained a comfortable Chelsea win, and one to leave head coach Lampard eyeing an upturn in home form.
Hudson-Odoi needed just six minutes to set Chelsea rolling, cutting in off the right flank to drill past Forest goalkeeper Jordan Smith at his near post.
The young England forward then produced a fine defence-splitting pass for Pedro, but the Spaniard could only strike Michy Batshuayi's heel.
Had Pedro been able to whip the ball around the Blues' Belgium striker, he would likely have doubled the hosts' lead.
Forest battled to make that reprieve count, and thought they had won a penalty when 17-year-old Alex Mighten drew a foul from Fikayo Tomori in the area.
Referee Peter Bankes pointed to the spot, only for the penalty to be chalked off by the VAR for offside.
Chelsea were in no mood to waste their own let-off, and promptly regained control.
Barkley angled a raking ball out to Hudson-Odoi on the right and he cut into the area again before firing across the face of Smith's goal.
A sloppy parry gifted Barkley a tap-in, and the Blues a 2-0 lead, just past the half-hour.
Chelsea eased to the break in complete control and were hardly troubled after the interval either.
Even when Yates nodded home a Forest free-kick, the offside flag came to Chelsea's aid.
Hudson-Odoi continued to raid the flanks, whipping in several dangerous crosses. Batshuayi certainly should have buried the best of the lot, but he could only hack high and wide.
