United's U21s ended a three-game losing run, with a hard fought goalless draw against Millwall at the Lions Bromley training ground on Monday afternoon.
It was a game of few clear cut chances, although United hit the woodwork twice and the hosts once on a chilly afternoon in the capital.
The Blades were quickly out of the blocks and rattled the crossbar as early as the 7th minute through Connor Dimaio.
Millwall first opportunity fell to Alfie Pavey, whose well hit volley struck the foot of the post. The striker also went close for the Lions in the second-half, but his angled drive went wide of Eastwood's far post.
Moments later, Dominic Calvert-Lewin again hit the woodwork, before Millwall's Callum Webb drew a smart save from the Eastwood as the spoils were shared.
Coach Chris Morgan said: "It was an enjoyable game, very competitive with both sides giving their all. There were chances and if any of the teams were to be disappointed not to nick the win it would be us."
United: Eastwood, Scarisbrick, McFadzean, Dimaio, Collins, McGahey, Hardy (Kelly 68), Whiteman (Cockerline 82), Calvert-Lewin, K. Wallace, Hamilton.
Unused: Evans, Ramsdale.
