Odion Ighalo scored twice as Manchester United eased to a 3-0 win at Derby and into the quarter-finals of the FA Cup
Wayne Rooney's presence in the Derby team dominated the build-up but Luke Shaw's opener and a goal in each half from Ighalo took the game away from the Championship side
The win extends United's unbeaten run to nine games and with a last-eight tie against bottom club Norwich to look forward to there will be hope of FA Cup glory in May
Rooney was Manchester United captain the last time that the club lifted the trophy in 2016 but he had only a booking and a warm reception to show for his efforts on a night when his new team were outgunned
Derby, mid-table in the Championship, had hoped for better having come into it unbeaten in front of their own fans since before Christmas and there were positives early on
Louie Sibley fired a left-footed shot just wide of Sergio Romero's post inside 10 minutes to get the home support involved and Rooney himself went close soon after
After Sibley had been cynically fouled by Shaw, United's all-time top scorer whipped in a free-kick that looked likely to creep in at the near post only for Romero to push wide
But much of the slicker work from the outset came from the Premier League team with Bruno Fernandes and Juan Mata at the heart of United's good build-up play
A poor touch from Max Lowe allowed Ighalo to sneak in between two markers but his powerful shot struck goalkeeper Kelle Roos and Derby went unpunished
The shots kept coming and moments later United had their breakthrough goal
Jesse Lingard and Fernandes both had efforts blocked in the same phase of play before Shaw's attempt bounced into the ground and over the head of Roos
Pride Park was left stunned and Derby needed to regroup but instead, Phillip Cocu's side found themselves two down before the interval
Ighalo showed great strength inside the penalty box before depositing the ball low into the corner of the net for his second goal in just his second start since arriving last month
When Tom Lawrence was forced off injured, all hope seemed lost as the United fans sang of Wembley but Max Bird and Martyn Waghorn did go close early in the second half
It was Solskjaer's side doing most of the pushing though with Fernandes' clever ball almost earning the impressive Shaw his second goal of the game
Instead, it was Ighalo who became the two-goal hero after seizing upon Mata's pass and blasting the ball past Roos left-footed at the second time of asking
There was still time for substitute Jack Marriott to force a fine save from Romero but any prospect of a comeback had long since disappeared by that point
All that remained was for the visiting fans to hail their former hero Rooney and there was the tantalising prospect of some late excitement when Derby won a free-kick
"If Rooney scores, we're on the pitch," chanted the away fans and it felt as if everyone in the ground wanted him to score - with the exception of Romero who tipped his fierce strike over the bar
It was a night when Manchester United had one eye on the past - and another on a future trip to Wembley
 "The difference in speed of passing, the limited time you have when you receive ball, for our team, and especially the youngsters, it was a great experience
 In the end, you have to give credit to Manchester United
 They deserved the win
 They were much better than we were
 But I think we deserved a goal
" "I was very pleased with the performance and very pleased to go through
 You never know away from home, being the favourites and having [Manchester] City on Sunday, how that will affect the mindset but it was professional
"We have found form
 We are defending well
 Clean sheets, that's massive for us
 It's seven in nine, that's important, and the two we have conceded we shouldn't have conceded
 I have got good players and they are in form
"Wayne Rooney would have dreamed of scoring the winner and upsetting Manchester United in his new home, but it wasn't to be for the Derby skipper
There was adoration from all sides of the ground, with the visiting contingent from Man Utd particularly vocal throughout the second half
 Rooney will know more than anyone, though, that it would have been different if his Derby side had been able to compete with their visitors
That does not mean there were not moments of magic from Rooney and there were plenty of times you could see his quality on the ball, as well as the desire he's always had
The two free-kicks were the moments when the crowd held their breath and just wondered if there was to be a standout moment, but that was not the only time he was at the centre of proceedings
An early tackle brought a huge roar from the home crowd, while one later in the half stopped a breakaway United attack in its tracks and earned Rooney a booking
 Far from the first of his career
Shortly after tracking back into the box and intercepting a Bruno Fernandes ball that looked set to be swept home by Juan Mata, there was a wonderfully weighted ball between Victor Lindelof and Luke Shaw that found Jack Marriott, whose first-time effort forced Sergio Romero into a smart save
Surrounded by fresh-faced teenagers, a 34-year-old Rooney is far different from the man who scored more than 250 goals for United during his time from Old Trafford
 But as the visiting faithful labelled Rooney "The White Pele", there were moments when everyone remembered his glorious past
After marking his first Manchester United start with a goal against Club Brugge, Ighalo's second start brought two more goals to see off Derby
 The former Watford striker was derided as a panic buy before he had even kicked a ball but even panic buys can come good and the Nigerian has already shown what he can in front of goal
"He is doing what it says on the tin and what we asked for when we signed him," said Solskjaer afterwards
 "He is experienced and he has scored goals all of his career
 He is in and around the box, he reads it, he sniffs out where the chances will come
 I think that striker is vital for a team
"Derby are back in Championship action on Sunday as they play host to Blackburn Rovers at Pride Park
