St Johnstone manager Steve Lomas believes his team were not focused enough as they crashed to a 3-0 home defeat by Motherwell.
"I just think the whole mindset of the players wasn't the same as it was for the last three games," he said. "But the good thing about it is that we've got Aberdeen on Tuesday night to turn that around.
"Our performance was not what it usually is in terms of winning individual battles. Motherwell won most and that's why they won the game."
The McDiarmid Park side now trail their third-placed Scottish Premier League rivals by seven points.
Lomas admits his team were way off the pace at McDiarmid Park and said: "The days when you're lacking a bit of creativity, you've got to be sound at the back and hopefully keep it tight. Unfortunately, we did neither of the two today.
"You've got to earn the right to play and Motherwell did that better than us.
"We have a few injuries - not wanting to make that an excuse - and we're hoping to get as many as we can back as soon as possible.
"That's football. Three weeks ago we had a full squad, three weeks down the line you're missing six or seven players, which does hurt you at times.
"That's not taking anything away from the lads that have come in, because I think the team as a whole weren't like they normally are."
