How the match unfolded
Yoane Wissa and Keane Lewis-Potter came into the Brentford side looking to step up in the absence of the injured Bryan Mbeumo, while the Bees were boosted by Christian Norgaard’s return from suspension.
Substitute Anis Slimane missed a huge chance in the 56th minute to double Sheff Utd’s lead as he shot straight at Flekken from point-blank range after Cameron Archer had won the ball high up the pitch and teed up his team-mate.
Flekken was forced into another save with 10 minutes to go when Archer went through on goal. Archer overpowered Ben Mee to get to a loose ball but could not beat the goalkeeper with his shot.
Slimane burst into the box just a minute later as the Blades pushed hard for a second goal, but the Tunisian could only find the side-netting from a very tight angle.
The Bees threw everything at an equaliser but fell short in the end despite efforts from Wissa and Mee.
Sheff Utd are still bottom with eight points. Brentford remain 11th but are level on 19 points with three other teams.
