Chris Wilder was left ruing Sheffield United's profligacy as his side slipped to an opening-day defeat at Bolton this afternoon.
United lost 1-0 to Bolton thanks to Jay Spearing's stunning volley, and an early spell of away pressure ultimately counted for nothing.
And Wilder, whose side were backed by over 4,300 fans over the Pennines, said: "I'm obviously disappointed, we had the lion's share of the play in the first half and should have been out of sight in the first 20-25 minutes.
"We started well, on the front foot, but a wondergoal changed the complexion of the game. Then we started the second half well and had enough of the ball in good areas, without showing the quality we have with the final pass.
"Bolton are an experienced team and had to defend deep, whereas we didn't really have to do that. But ultimately, we're very disappointed. We're in a results business and we haven't got one today."
Wilder reserved special praise for the supporters who travelled to follow their side, with 4,357 packed in the away end.
"It was a massive following, and we have to keep them on side," he added.
