Stoke City boss Tony Pulis admitted he was left frustrated following the 2-0 defeat at Swansea on Sunday.
The Potters enjoyed large spells of possession and saw shots cannon back of the woodwork twice, while efforts from Scott Sinclair (pen) and Danny Graham ensured the Welsh outfit took the points at the Liberty Stadium.
Disappointed with the result, Pulis believes defeat showed the tight margins that teams face in the Barclays Premier League,
"It really shows the fine line between success and failure," Pulis told the official Stoke website.
"Between their two goals, we looked the side who were more likely to get the next goal in the game and we had some good chances when luck wasn't on our side.
"We hit the woodwork twice and who knows what might have happened if one of those had gone in, while I also felt we should have had a penalty. The challenge on Jon Walters was as good as our forwards on the Fiji players in the Rugby World Cup.
"The only save Begovic had to make was one midway through the second half, but other than that they didn't have many other opportunities."
However, a sluggish start also played its part in the Potters finding themselves behind at the Liberty Stadium, an unusual trait for Pulis' well-drilled side.
Whilst the manager will be eager to get that out of the team's system, he accepted that it was simply 'one of those days' on Stoke's travels.
"We've had two slow starts now, one at Sunderland and one here now. It's difficult lifting the players psychologically when it's our third game in a week and they certainly looked a little leggy in the opening stages; something we need to take a look at," he concluded.
"It was a poor challenge from Ryan, one he didn't need to make because the lad was running away from goal. That gave Swansea the start everyone wants.
"After that, we were nice and bright, but we couldn't make the chances count. How that one from Crouchy at the end didn't go in really summed up our day."
