Chris Morgan says youth will have a part to play in the forthcoming play-off campaign.
Since assuming responsibility of first-team affairs, Morgan has handed first league starts to Callum McFadzean and Joe Ironside, in addition to giving Elliott Whitehouse and Jordan Chapell valuable game time.
The youngsters have impressed United's temporary leader and speaking after the stalemate with Preston North End, he commented:
"I look at Joe (Ironside) and as a defender I know what they don't like; he is a real pest and never gives them a moment's rest. We all know Joe can pin his marker and hold his own physically but on Saturday he showed he is more than capable of getting in the right positions and being a real threat in front of goal.
"I thought he was excellent alongside Dave (Kitson) and Joe grew as both a man and a player, which is immensely pleasing and very encouraging for the future."
He continued to heap praise on United's exciting prospects, adding:
"Callum (McFadzean) was excellent at Crewe and I wanted him to see him play at Bramall Lane, the same goes for Elliott (Whitehouse).
"Terry (Kennedy) and Aaron (Barry) have been on the bench and that emphasises how hard these youngsters have worked for the opportunity.
"Ultimately these lads are going to have a big part to play in the future and that includes the remaining games this season."
