Blackpool FC player ratings: New signing among four players to score 8/10 in EFL Trophy win against Barrow- in pictures
Sonny Carey and Kylian Kouassi were both on the scoresheet for the Seasiders at Holker Street.
Neil Critchley made nine changes to the side that overcame Wigan Athletic at the weekend, with only Callum Connolly and Jensen Weir remaining in the starting 11.
Blackpool dominated the first half, but struggled to create too many clear opportunities.
Dembele fired a couple of shots off target, while Owen Dale had an attempt deflected wide.
The opener eventually came in the 44th minute, with Carey calmly moving the ball onto his right foot before curling a shot past Josh Lillis.
In the second half, Barrow gave the Tangerines a much sterner test.
The closest chance they had came through Courtney Duffus, who forced a superb save from Richard O’Donnell.
Despite the Bluebirds’ pressure, the Seasiders were able to confirm the victory heading into the latter stages, with Kylian Kouassi marking his debut with a goal, after a good break down the right side from Albie Morgan.
