Chelsea produced one of their best performances of the season as they won 3-1 at Aston Villa to book an FA Cup fifth-round tie at home to Leeds United.
Conor Gallagher opened the scoring on 11 minutes, stroking the ball into the top-left corner from Noni Madueke's pass for his first goal of the season.
Chelsea doubled their lead 10 minutes later as Nicolas Jackson headed in from Malo Gusto's cross.
Enzo Fernandez all but ended the contest nine minutes into the second half, curling a superb free-kick into the top-left corner from 25 yards out, beyond the reach of compatriot Emiliano Martinez.
Villa substitute Moussa Diaby grabbed a consolation goal in the first minute of stoppage time, his shot hitting the inside of a post before going in.
Unai Emery's men will hope to bounce back from their cup exit when they entertain Manchester United on Sunday. Chelsea, meanwhile, travel to Crystal Palace on Monday night for a London derby.

Forest through to face Man Utd
Nottingham Forest set up a fifth-round tie at home to Man Utd after scraping past Championship side Bristol City on penalties.
Forest went in front after only eight minutes through Divock Origi, who bundled in after Felipe flicked on Morgan Gibbs-White's corner.
But Bristol City captain Jason Knight levelled when he prodded in from close range six minutes later.
Neither side were able to find a winner inside 90 minutes, and after Nakhi Wells and Matty James missed the best chances during extra-time for Bristol City, the match went to a penalty shootout.
Matt Turner saved Sam Bell's spot-kick, handing Forest the advantage, and Taiwo Awoniyi, who has featured in Forest's last two Premier League matches since returning from a 10-week layoff, scored the decisive penalty as Forest won the shootout 5-3.
Forest are back in Premier League action on Saturday, when they host Newcastle United.
