Forest now have to go to Bramall Lane, a ground that should send shivers down Paul Hart's back as the Blades not only beaten Forest but have beaten Leeds United (twice), Sunderland and Liverpool convincingly at the ground.
To make life difficult for the Reds is the fact that defender Michael Dawson will not play the second leg after receiving a straight red card after producing a dreadful challenge on Steve Kabba with just six minutes to left.
At half-time the score was left goalless but did not damper the atmosphere as the City Ground was sold out with a 29,064 crowed, 4,500 of them coming from Steel City.
Forest's top goal scorer shot over the bar and Harewood shot wide from a acute angle, this frustrated the visitors as they failed to create chances.
the home side pilled on pressure and almost took the lead when Andy Johnson got onto end of a cross where Paddy Kenny managed to hold onto Johnson's header.
The first goal of the game came when Phil Jagielka passed a awful ball in midfield straight to Andy Reid who put in a long pass towards striker David Johnson who was unmarked and only had Kenny to beat.
However, three minutes later the Blades hit back. Dean Windass worked ball around 18 yard box and few passes later found Michael Brown but Matthieu Louis-Jean hacked down the midfielder. Michael Brown obliged by sending keeper Ward the wrong way before Dawson was dismissed.
