Bissouma’s near 30-yard effort which found the top corner in the 27th minute. Combined with a deflected Mac Allister strike was enough for the Seagulls to run out 2-1 winners.
The visitors Blackpool, were forced into seven changes to the side that beat West Brom on penalties in the last round, after a Covid-19 outbreak in the squad.
Brighton controlled the first half and were deservedly ahead courtesy of Bissouma’s wonderful strike. It was the French midfielders fourth goal for the club – all of them coming outside the box.
However a defensive lapse allowed Blackpool’s Madine to get on the end of Garbutt’s cross and level matters on the stroke of half-time.
The Seagulls came out strong in the second half, with Mac Allister going close early on. Brighton then deservedly retook the lead as Alexis Mac Allister’s shot deflected in off Steven Alzate after 58 minutes.
The Seagulls had plenty of chances to put the game to bed, with Maupay and Propper going close. Brighton hung on to set up a 5th round tie against Leicester.
Speaking to BBC Sport Brighton manager Graham Potter spoke of his frustration with Bissouma’s shot taking up to his goal:
“We were getting a bit frustrated with Bissouma because he had a couple of shots before that that were scuffed along the floor.
“And, when he shot, I was nearly close to getting frustrated again and then you see it fly in the top corner and it’s hard to argue with that.
“I thought we controlled the game but while it’s only by one goal, anything can happen, especially in this competition.
“Credit to Blackpool, they were organised, and it’s nice for us to go through.”
Next up for Brighton is a massive game against a Fulham side one place below them in the table. Wednesday 27th, kick off 19:30.
