Motherwell manager Ian Baraclough bemoaned his side's ongoing set-piece frailties after losing 2-1 at home to Aberdeen.
Ash Taylor scored the winning goal for the Dons from a Niall McGinn free-kick.
"I'm sick of coming in having lost a game on what really is a set piece," Baraclough told BBC Scotland.
"We've got to realise that set plays are a big part of the game and, for all our good play, you switch off for a second and you can lose a game."
Motherwell took the lead in the first half through Marvin Johnson and competed well against an Aberdeen outfit that aims to challenge Celtic for the Premiership title.
Baraclough's men, however, have now suffered three straight defeats after an opening victory.
"Having said that, we've matched them shot for shot," said Baraclough. "We've had just as many attempts on goal, we've played a very, very good side there and come away feeling sorry for ourselves and licking our wounds.
"If we play like that, more often than not we'll end up winning games."
Dons boss Derek McInnes was not pleased by the visitors' early display at Fir Park, but in contrast to Motherwell, his side have now won all of their opening league matches.
"To go behind was really disappointing," said McInnes. "We lost a really poor goal and at times our defensive work as a team was a bit too open - and it gave Motherwell encouragement.
"Going forward, I thought some of our play box to box was outstanding in the first half - the movement, dominating possession, getting into good areas."
Last season, Aberdeen endured a stuttering start to their domestic campaign but emerged strongly to finish second to Celtic.
"We shouldn't shy away from that challenge," added McInnes. "Last season, there was a lot to like about the team.
"We were pleased, but we never won a trophy, never took it all the way.
"It took us until October to get any rhythm last year, so the start is very pleasing.
"It is only a start, but if we can get into a winning run and a consistent run from now, it should serve us well going forward."
