Manager Stuart McCall was delighted with his defence as Motherwell stayed top of the Scottish Premier League with a last-gasp win at St Mirren.
"We come into to every game with confidence," he said after Tom Hateley's injury-time winner.
"Our middle to forward players didn't play as good as they could but we defended really well.
"The back four were exceptional. It was a hard-earned clean sheet. Four clean sheets on the bounce is terrific."
The match seemed destined for a goalless draw after home goalkeeper Craig Samson had made a series of good saves to deny McCall's men.
But the visitors snatched maximum points when Hateley curled in a sweet free kick with almost the last kick of the ball.
"It's a sickener for any manager when you lose a last-minute goal I feel for Danny (Lennon) and St Mirren because they played their part in an entertaining game," McCall told BBC Radio Scotland.
"Over the course of the game, I think Dazza's (Darren Randolph) had one reasonable save to make and their keeper has had three or four excellent saves.
"It was end-to-end but we certainly had the better chances."
St Mirren disputed the decision that led to Hateley's decisive strike and McCall had sympathy for the home side
"I've looked at it again and I can understand why St Mirren might be angry," he explained.
"Gary Teale definitely gets the ball but he takes Nicky Law as well. If I was playing, I'd be very disappointed but that's just how the rules are these days."
McCall repeated that he is looking to add to his squad and is seeking cover for long-term injury victim Steven Saunders.
"We were looking for a centre-half who could cover at left-back and now we are after a centre-half who can play at right-back," he said.
"And I think we could do with a forward wide player who could come off the bench and do something.
"We're looking at a few things but we have to make sure we get it right because we only have a little bit left for wages and a thin squad."
