Morgan, United's captain, has picked out front-man Darius Henderson as the Blades' main threat this season, and knows that the former Watford man can fire on all cylinders.
Morgs said: "Our key man will be Darius Henderson. I think if we can keep Darius fit and give him the service, I think he'll be the man to get us the goals. At the back end of last season we was patching him up and he was just playing so he'd contribute to them team, even though he was injured.
"We looked after him in the summer, and I'm sure the people around him, whether it be Ched, Billy or Jamie, will feed off him and do well."
Hendo bagged seven goals in all competitions last year, but was disrupted with a number of injuries and two red cards!
