Chelsea made it to the quarter-finals of the Carabao Cup on Wednesday, with the Blues defeating Derby County 3-2 in the fourth round at Stamford Bridge.
An own goal by Fikayo Tomori gave the hosts the lead after just five minutes, but Jack Marriott immediately equalised for Frank Lampard's outfit.
Richard Keogh became the second visiting player to put through his own net after 21 minutes. However, Derby once again found a swift answer to make it 2-2 through Martyn Waghorn.
Cesc Fabregas made it 3-2 to Chelsea shortly before half-time, and despite a strong second half from Lampard's side, the EFL Championship club were unable to grab a third equalising effort.
