This was the sixth game in this league season that hasn't yielded a win, but it might to be the sorest for Aberdeen.
Up until this, Thelin has been stubborn - much to the frustration of fans - and stuck with his 4-2-3-1 system. At last, he changed his approach and to some avail.
Even after a gut-wrenching finale, supporters will see this as a much-improved performance.
A speedy start, during which saw Kevin Nisbet forced Calum Ward into a save inside 40 seconds, suggested this might just be the game their fortunes flipped.

It took time for Jens Berthel Askou's side to kick into their free-flowing play - which should have earned them a league win before now - but their patience paid off.

Deserved back-to-back wins can do wonders for this Motherwell side, who continue to impress in invention and determination.
