Tammy Abraham scored a hat-trick as Chelsea booked their place in the FA Cup fifth round after a 3-1 win over Luton at Stamford Bridge.
The striker netted twice in the opening 17 minutes before the visitors hit back with a strike from Jordan Clark.
However, Abraham completed his treble with 16 minutes to go to set up a trip to Barnsley in the fifth round for Frank Lampard’s men.
Mason Mount captained Chelsea for the first time as Lampard made seven changes for the tie.
Billy Gilmour started in midfield as Lampard fielded a strong side as expected, given the Blues’ current struggles.
Kepa Arrizabalaga was handed a rare start in goal, while Timo Werner partnered Christian Pulisic and Tammy Abraham in a front three.
Full-back Kal Naismith made his first start for Luton.
Abraham fired Chelsea into an early lead on a snow-covered Stamford Bridge pitch.
The England striker latched onto Werner’s cutback to slot home and put Chelsea 1-0 to the good just past the 10-minute mark.
Abraham quickly put the home side 2-0 up with a fine header, turning in Reece James’ smartly-lofted cross.
Jordan Clark then slotted home for Luton on the half-hour mark to keep the visitors in the tie.
