Brighton and Hove Albion reached the quarter-finals of the FA Cup for the second season in a row with a 2-1 win over Derby County.
First-half goals from Anthony Knockaert and Jurgen Locadia sent Chris Hughton's side into the last eight in comfortable fashion against Frank Lampard's men.
Ashley Cole scored his first goal for the club to halve the deficit, but Derby failed to repeat the comeback from 2-0 down that they produced twice against Southampton in the third round.
Brighton dominated the first half and deservedly took the lead 33 minutes in, when Knockaert swept home Yves Bissouma's cross for his second FA Cup goal of the season.
