Takeaways from the game
There will be plenty to takeaway from the game for Brighton. The first of these is Knockaert, who looked to be back to his best form against The Championship side.

He then opened the scoring with a superb curling shot into the bottom right corner.
Knockaert nearly made it three, when Locadia played the ball to the winger and he drove at the Derby defence, but his curling effort was well saved by Roos.
Derby will not have an awful lot to take away from the game. The only thing is that they did not take their chances.
Before the Seagulls doubled their lead, Waghorn had a great chance to level the match, but his effort was tame and straight at Button.
Something to take away for the Rams is they got to see the long-awaited debut of former England left-back, Cole.
The left-back showed some glimpse of his quality and experience during the second half and he will be a useful addition in their bid for promotion to the Premier League.
He then made his debut even better by pulling back a goal with nine minutes to go.
Man of the match
There were plenty of choices for man of the match, but it has to go to Bissouma.
The Mali midfielder was outstanding throughout the game, he set up the second goal of the game with his curling effort which came off the post.
His work-rate, energy in the middle of the park and willingness to quickly turn defence into attack was a key feature for Brighton.
Bissouma combined his pace and skill to break-away and work his way towards the box and at the age of just 21, he has a bright future ahead of him.
However, the midfielder will not be able to play in the quarter-finals, after he picked up his second yellow of the competition.
The midfielder was taken off with five minutes to rousing applause by Albion fans.
