Town will travel to Sunderland in the youth cupFleetwood Town's youth team booked a third round date away at Sunderland after seeing off Sheffield United in the FA Youth Cup at Highbury on Tuesday evening.
United opened the scoring through a close range header from Dominic Calvert-Lewin on 21 minutes, before Shane Glean restored parity for the Cod Army when he drilled the ball into the top corner a minute later.
Louis Myers made it two five minutes after the break with a 25 yard effort, and Jordan Hancox netted from close range to wrap up the tie.
Liam Bleeker returned in goal for Craig Madden’s men, while Joe Gregory and Liam Wood partnered each other in midfield for the young Cod Army.
In an even start to proceedings, Conor Smith bent his right-footed free-kick into the wall, and Bleeker was forced to smother the ball from Calver-Lewin after the United man had been put through on goal.
Town fullback Danny Williams then turned provider, as he drilled in a fizzing ball which evaded everyone in the box in what was a bright first opening 15 minutes for the hosts.
The Blades took the lead in the 21st minute through Calvert-Lewis, who headed in from close range after Kler Heh's cross had cannoned back off the post.
However, Fleetwood were level immediately after, with Glean equalising for the hosts.
He was played in on goal by Smith, with the midfielder drilling the ball powerfully into the top corner and beyond the dive of Jake Eastwood.
Bleeker then had to deny Calvert-Lewin with a smart low save, before the same man glanced just over the bar from a corner shortly after.
Town then went agonizingly close to going in front, as Smith rattled the crossbar from 30-yards out before being hacked to safety by Shea Gordon.
As the second half resumed, Fleetwood got their noses in front courtesy of Myers.
Myers received a pass before taking a touch and curling the ball into the top corner from 25 yards.
Town's lead would be extended just two minutes later, with Jordan Hancox bundling the ball over the line after Blades keeper Eastwood could only parry a long range effort.
Fleetwood forward Jonny Conway perhaps could have added a fourth after 56 minutes, however he blazed the ball over the bar.
Bleeker was then on hand to keep out a deflected long-range effort from Joe Cheeseman, while skipper Michael Muscat’s his dipping free-kick skimmed the top of the bar for Town.
With eight minutes to play, Bleeker kept out Calvert-Lewis with a superb low stop from close range, and despite some late pressure, Madden's side hung onto claim their place in the next round.
