Chris Wilder looks ahead to the trip to the City Ground
United suffered defeat on the eve of the international break but only after a tremendous effort at Forest on Saturday.
John Lundstram scored an early goal and Cameron Carter-Vickers saw an injury-time header strike the woodwork
Wilder freshened his team. For the fixture down the M1, Lundstram, Duffy and Donaldson started and one made an instant impact! Clarke, Wright and Brooks dropped to the bench.
For the first two minutes, Forest barely made it out of their half. O'Connell was constantly on the attack and Duffy, Fleck and Coutts saw plenty of the ball. But the opening goal, just as the game entered the third minute, saw Stevens make space for himself on the left and deliver a low cross for the arriving LUNDSTRAM to sweep home from just inside the box.
The start, by both sides, was high-energy and Forest levelled with their first serious foray into Blades territory. Following a poorly-executed corner by the home side, Fleck's pass was cut out by CUMMINGS, who fired beyond Blackman's right arm.
The action-packed start continued with United enjoying the better of the chances. Again Stevens found space on the left but this time Duffy's effort was blocked and Lundstram fired wide after cutting back onto his left foot.
On 19 minutes, the ball was in Forest's net again but the lead was not restored. A curling cross from Duffy may or may not have been touched by an offside Baldock but an assistant official's flag was raised.
United were doing most of the attacking but Forest were clinical when they crossed the halfway line and went ahead on 27 minutes. From Darikwa's deep cross, Murphy side-footed back into the danger area and DOWELL's first time effort was placed into the bottom corner.
Shots from Duffy and Fleck were straight at goalkeeper Smith in response but the Blades were dealt a further blow when Baldock went down injured and needed to be replaced. Wright was introduced and Basham was redeployed down the right.
Late in the half the better of the chances belonged to Forest. Blackman parried away a Cummings shot after O'Connell prevented Murphy getting to a Traore cross, Murphy then headed over and the striker put an opportunity on a plate for Cummings on the right but the subsequent shot was wide.
There was one more chance in the four minutes of added time but the build up from Fleck, Duffy and Lundstram resulted in Basham's shot being deflected wide.
The early chances in the second half went Forest's way. Osborn's off-target shot deflected off Carter-Vickers and rolled just wide of Blackman's right post and then Bouchalakis headed wide a deep cross, prompting boss Wilder into a couple of changes - Clarke replacing Donaldson and Brooks taking over from goalscorer Lundstram.
Duffy failed to hit the target from range but United got back on top - there was a nervous moment for goalkeeper Smith as Brooks almost charged down a clearance.
Dowell fired over for Forest when they had numbers over following a break on 74 minutes and the action remained fast-paced as the final 15 minutes approached.
A free-kick routine saw Fleck and Coutts almost put Duffy in but Forest repelled the effort and with five seconds of normal time left Smith produced an acrobatic save to keep out a Duffy shot.
United went closer still in injury-time when a Stevens cross saw Carter-Vickers rise highest but his header struck a post and the goalkeeper before Forest scrambled a clearance.
Very late on Forest managed the game well in terms of keeping possession to hold on for the points, but there was a standing ovation from the Blades fans as the players left the pitch.
