A JAVIER Hernandez brace and late strikes by Phil Jones and Fabio saw Manchester United progress in the Capital One Cup with a 4-0 fourth round win over Norwich City.
Second-half injuries to wingers Robert Snodgrass and Nathan Redmond were a further cause for concern ahead of Saturday's return to Barclays Premier League action at Manchester City.
Chris Hughton made eight changes to his side from Saturday's Premier league draw with Cardiff City.
Mark Bunn recovered from a hand injury to play in goal, with Steven Whittaker, Ryan Bennett and Javier Garrido coming into defence to join Sebastien Bassong. Bradley Johnson replaced the injured Alexander Tettey - Nathan Redmond also started with Wes Hoolahan playing in-behind Johan Elmander upfront.
A strong bench included Russell Martin, Jonny Howson, Gary Hooper, Anthony Pilkington and youngster Josh Murphy, whose stunning goal set the Canaries on their way to their 3-2 win over Watford in the last round.
The opening five minutes saw Ashley Young involved for the hosts firstly with a free-kick and then releasing Hernandez into the box, but the Canary defence saw off any threat comfortably.
Ten minutes in and Redmond made a purposeful run resulting in a turn and shot outside the area which whizzed past Lindegaard's post.
The best chance of the game so far fell to United after 13 minutes. Zaha making a break down the right and putting in a cross for Hernandez who looked to have turned Bennett, but the City man got a foot on the ball and it deflected wide. The Mexican was then involved moments later heading high over the bar under pressure from Johnson.
Johan Elmander won the Canaries a corner after his shot deflected off Vidic, unfortunately Snodgrass' resulting flag kick was cleared.
But on 19 minutes the hosts were awarded a penalty when referee Kevin Friend deemed Leroy Fer had caught Adnan Januzaj as he looked to play the ball on the byline. Hernandez stepped up and coolly slotted past Bunn for 1-0.
Having scored now in his last three Capital One Cup outings the Mexican was involved in another United attack - this time rising to meet an Ashley Young free-kick, which he glanced into the waiting hands of Bunn.
At the opposite end the goalkeeper was then called upon to defend a Canary set-piece, Ryan Bennett heading Snodgrass' whipped left-footed delivery into the arms of the grateful Lindegaard.
Ten minutes to half-time and Januzaj curled a shot just past City's far post after a Red Devil's break from midfield.
Redmond made another run forward cutting inside from the left but under pressure from the United defence he couldn't get any power on his shot and it ran harmlessly through to Lindegaard.
With a minute of the half remaining Whittaker and Bassong were called upon to make important blocks from Januzaj as he looked to add to United's lead.
Half-time: Manchester United 1, Norwich City 0
Two minutes into the half and City were awarded a free-kick for a foul on Redmond. Snodgrass delivered the ball to the back post where Bassong was denied a clear header by Vidic. Fer then headed over another set-piece a minute later as City looked to make the most of some good possession.
Elmander did well to stretch to get a touch on a good Nathan Redmond cross from the left as the youngster had broken into space, but the Swede's shot flicked just wide.
But on 53 minutes United had doubled their lead when Buttner crossed for Hernandez to head goalwards, Mark Bunn initially keeping the ball out but the Mexican was the first to react to knock the rebound into the net.
Three minutes later and the Canaries responded with a great chance - Snodgrass fed the ball out to Redmond on the right and the England youngster put a cross in for the Scot whose header was met by the Danish goalkeeper. It was a brave effort by Snodgrass who collided with Rafael and had to receive lengthy treatment in the goalmouth before being stretchered off to be replaced by Anthony Pilkington.
With 20 minutes left Januzaj tried his luck with a long-range effort which zipped along the wet surface and past the post.
A further injury concern came for City as Nathan Redmond pulled up on 75 minutes with what looked like some sort of muscle strain - on came Josh Murphy for the final 15 minutes of the game.
David Moyes' made his first substitution of the game with 12 minutes remaining replacing youngster Zaha with Wayne Rooney.
The game was put to bed by the hosts in the 87th minute when Phil Jones did well to collect a Bassong clearance to hit home their third.
Two late changes were made - Gary Hooper coming on for Hoolahan for City and Anderson replacing Cleverley for United.
With the length of treatment given to Robert Snodgrass eleven minutes of stoppage time were awarded.
The late substitution of Fabio for Januzaj then proved an inspired one as the defender immediately raced onto a Wayne Rooney long-range pass to slot home United's fourth and see them firmly into the next round of the competition.
