Chris Wilder was bitterly disappointed to leave Ashton Gate empty handed on Saturday afternoon.
Speaking after seeing Marley Watkins win it for the home side, despite his side creating a host of first-half opportunities, Wilder was understandably frustrated.
He remarked: "I'm certain if we'd got the first goal we'd have won the game.
"Every manager in the Championship says the same, score first and you win eight out of ten games.
"If you score first, the opposition must come out and then you can catch them on the counter. They brought on players like Watkins, O'Dowda and Taylor, good players in this division and they stretched the game.
"It was risk and reward for us once they scored, we had to commit bodies forward and change the shape to try and wrestle back the initiative and for the majority of the game it was one I didn't see us losing."
The Blades boss added: "It's fine margins in Championship football, but we have to be better in those scenarios though.
"They got their noses and saw it out well, but if we go one or two in front like we should have you see a totally different game.
"We can talk about individual performances and losing Flecky, but overall we probably just fell a bit short and we've lost a tight game, we don't like that feeling and we must get over it quickly."
