Nigel Clough has hailed the contributions of Ryan Flynn and Jamie Murphy.
The Scottish duo have been instrumental in United's 11-match unbeaten run and have played major roles in the road to Wembley in the FA Cup.
Speaking ahead of the weekend's home encounter with league leaders, Wolves, the Blades boss commented: "In my opinion, we have got two of the hardest working widemen in the league in Flynn and Murphy.
"They have taken the baton and are vital parts of what we are trying to achieve. The way we play suits the team, those two especially, and we have reaped the benefits of that.
"As a team, we rely on their energy, them getting forward and delivering crosses. We have won ten straight games recently - you don't do that without creating and those two have been an integral part of that."
Around the turn of the year Murphy scored three times in six appearances, Flynn has chipped in with three goals in five starts recently and the duo have 12 assists between them this season.
