Ahead of Saturday's Yorkshire derby against Bradford City at Bramall Lane, Nigel Clough has again outlined the importance of skipper Michael Doyle to the Blades.
Clough is full of admiration for United's on-field leader, commenting: "Michael is an important figure here. He's got experience and a very professional attitude to his job.
"That's one of the reasons why, perhaps, he also performs to a consistent level. We know what we are going to get from Michael pretty much game in, game out, which for a manager is a good quality to have.
"Michael might not win many awards, because he might not create many goals, but the job he does for us out there is crucial and he does it well.
"He breaks up attacks, even just by getting a toe in sometimes to knock away the ball, but his reading of the game allows him to be in the right place at the right time.
"Then, he'll give that simple little short pass which gets us going forward and, although some people might not realise it, often those are the most difficult ones to get right."
The Gaffer also believes Doyle channels his aggression in a positive manner, in addition to leading by example: "We don't want people collecting cards willy nilly.
"We need to be competitive but in the right way. Not in a manner whereby it impacts upon the team because we need players to be available."
