After scoring early and gaining a 3-1 aggregate lead, the Reds were forced to take the game to penalties. Sheffield United improved during the second half and levelled the tie, with little separating the teams in extra time.
Game dynamic and refereeing display
Sheffield United set out to turn this game into a war.
From the start of the game, United players were leaving plenty on Forest players, without the referee Michael Oliver blowing his whistle.
Forest took a while to realise that the referee was going to let a lot of challenges go for both sides during the game, but it was working very well for United.
For the opening 90 minutes, the Blades pressed Forest at every opportunity, creating a hostile atmosphere for the Reds.
Samba the hero
In games of this magnitude, one player usually rises to the occasion and becomes a hero. That's exactly what Brice Samba did.
Throughout the 120 minutes of regular time, the Forest goalkeeper made some fantastic stops, including one from close range with his foot in the last stages of extra time.
The Forest fans sang 'Samba, Samba, Samba' as the game went to penalties, and the goalkeeper took his place in goal and saved the first penalty.
The Forest goalkeeper thrived on the crowd's chants and taunted the players taking penalties, tipping Conor Hourihane's onto the crossbar before saving Morgan Gibbs-White’s penalty to win the game.
On the night, Samba made four saves, completed one high claim, ten accurate long balls and made three significant penalty saves to take his team to Wembley.
Brennan breaks another record
The 20-year-old now has 19 goals and ten assists in all competitions this season. Only three players have scored more than 18 goals in a season for Nottingham Forest this century.
