Lee Carsley is adamant boss David Weir will prove himself to be a success at Bramall Lane, but insists United's current rebranding will take time to put into place.
Speaking ahead of Tuesday's Johnstone's Paint Trophy tie with Hartlepool United, Carsley remarked: "The Gaffer is a winner; he has played for two clubs in Rangers and Everton who aren't used to losing football matches.
"To play on Merseyside and for the Old Firm you have to have character and he has certainly got that in abundance.
"We know we need results but at the moment we are trying to change the whole brand of Sheffield United to make it something sustainable for the next 10-15 years, rather than the next 3-6 months.
"There is a real belief in what we are doing and the players are on the same page. We don't feel under pressure because hopefully everyone can see what we are trying to create, it is all for the good of the club, long-term.
"The Gaffer is a fighter, he won't walk away from a challenge or back down and I am the same, along with the rest of the coaching staff.
"Of course we know we have to win matches, but at the same time we have to strike a balance in how we achieve that to ensure it is entertaining for the supporters to watch."
