Yves Bissouma was the boss as Albion overcame injuries and illness to reach the quarter-finals of the FA Cup for the second year running.

The Mali midfielder set up both first half goals for Anthony Knockaert and Jurgen Locadia, the third for each this season, in the 2-1 win against Derby County in the fifth round at the Amex.

Chris Hughton's customary tactic of multiple changes in the competition was exacerbated by a knock that ruled top scorer Glenn Murray out of the squad and illness which sidelined Davy Propper.

Dutch midfielder Propper reported for the game and was due to start but had to be sent home.

Albion were already missing Solly March (ankle) and Florin Andone (ban).

Slight injuries also denied Hughton the option of using Lewis Dunk, Leon Balogun and Max Sanders on an inexperienced bench.

The subs included 19-year-old Norwegian defender Leo Ostigard and Irish midfielder Jayson Molumby, who only made a 45-minute comeback from 15 months out in the under-23s at Manchester City last night.

The Argus: Knockaert gave Albion a deserved lead in the 33rd minute (above), drifting in from the left to find space on the edge of the box to clinically convert a cut-back from Bissouma, who exchanged passes with Alireza Jahanbakhsh.

It was the type of finish Frank Lampard, now Derby's manager, produced with regularity in his playing career.

The lead was doubled in first half stoppage time. Locadia, playing through the middle in Murray's absence, slotted into the empty net when Bissouma got the better of Tom Huddlestone to curl a left-foot shot against the far post.

Lampard made changes at the break, bringing on Ashley Cole and Jack Marriott.

Derby came from two goals down twice in the third round at Southampton, while Albion have relinquished 2-0 leads in the Premier League this year at West Ham (drew) and Fulham (lost).

There was no repeat for either this time, although Cole set up a tense finish by pulling a goal back on 81 minutes, the seven-time FA Cup winner's first ever goal in the competition.

He nodded in from ten yards from Dan Burn's attempted clearance, with Derby appealing for a penalty for a foul by Bernardo on sub Florian Jozefzoon.

Albion's progress into Monday night's quarter-final draw came at further cost.

Bissouma is banned from the next round following his second yellow card in the competition, while Locadia limped off with a left leg injury sustained with no Derby player near him.
