Nigel Clough felt the Blades did more than enough to win their FA Cup first round tie at Crewe on Saturday, but is pleased enough to be in the hat for the second round following the stalemate.
Looking back on the goalless draw at Gresty Road, Clough was again happy to see his team dominant the game, although he was frustrated that elusive goal evaded them, despite numerous opportunities.
The Gaffer remarked: "It was a mirror image of the league fixture last month, the only thing that was missing was a goal.
"It was another excellent performance, we were composed and controlled the game from start to finish, limiting Crewe to maybe just one shot at Mark (Howard), but we are lacking that break in front of goal.
"It wasn't for a lack of trying or not creating chances though, Jose Baxter shots wide from 10 yards out, Diego (De Girolamo) goes very close and we also hit the bar.
"We could have been two goals in front in the opening minutes through Ryan Flynn, whilst Jamie Muprhy's disallowed goal is incredibly tight, on another day that decision goes our way and we win the game comfortbaly.
"We wanted to be in the hat on Monday and we are. We asked for a clean sheet, we got one, we are just disappointed not to have won the tie at the first time of asking."
