Barnsley manager Mark Robins was left to rue his side's slow start and the lack of a cutting edge in their 1-0 defeat at Watford.
John Eustace's early strike gave the Hornets all three points but Robins felt it could have been a different story if his side had been ruthless.
He said: "What was it (Eustace's goal)? 45 seconds, something like that. I thought we learned out lesson from the last game against QPR.
"Unfortunately we hadn't, they've not picked up properly and they've (Watford) got a habit of starting quickly and they've done that again today and won the game inside the first 45 seconds.
"Objectively we've done enough to win the game. What we haven't done is the all important thing and hit the back of the net with the ball.
"I think we've had upwards of 15 shots and 14, 15 corners and not managed to make one of those count. That's the disappointment. We've created enough to win three, four games but not done enough and hit the back of the net."
