United took an early lead through Anthony Dwyer's second in as many outings, but Rueben Rodrigues and an own goal from Mitchell Tait put County ahead at the break.

Debutant Macauley Langstaff added a third in the second period before defender Kyle Cameron looped a header home with 11 minutes remaining.

Cedwyn Scott added a fifth late on after good play by Cal Roberts.

In front of a packed crowd – eager to see the Magpies for the first time under new boss Luke Williams – the visitors started well and went close through Rodrigues before Matty Palmer skied over.

United defended resiliently for the opening stages and, on the break after just 14 minutes, went ahead.

A superb over-the-top pass from Tait saw Courey Grantham break the offside trap and his delicate lateral pass found Dwyer who slotted confidently beyond Sam Slocombe.

Lewis Carr had to be at his sharpest to deny Adam Chicken’s dangerous cross from finding Rodrigues, but a home lead was ultimately short-lived.

On the half-hour, the Portuguese benefited from a fortunate bounce after a goalmouth scramble to prod beyond Kieran Preston.

County did have the ball in the net again moments later, only for jubilant celebrations to be cut short, however another dangerous cross from the left saw the unfortunate Tait bundle into his own net 10 minutes before the break.

A host of changes saw a near-new side for Williams’ men take to the pitch for the second 45 and a recent recruit in Langstaff saw a free-kick harmlessly bend around Preston’s post six minutes after the restart.

But it wasn’t long before a third was added when Aaron Nemane’s direct approach saw him pull one back for Scott and a deflected strike eventually fell to Langstaff who slammed into the roof of the net.

Academy product Gianni Musson made only his second appearance for the senior side, replacing Preston with 71 played and there were more minutes for Ollie Clark who stepped up his recovery from injury.

Callum Frogson and Jordan Haywood secured more important game time - a testament to the academy pathway. Roberts’ dangerous cross was flicked over by Langstaff before Cameron's floated header dropped beyond the young Musson for a fourth.

With 82 played, another debutant in Scott took aim and fired low beyond the young 'keeper, possibly via a post, as County secured a first win under their new boss.

United are back in action on Friday night as they welcome Nottingham Forest U23s to Greenwich Avenue (7.30pm).
