Kevin van Veen broke St Mirren's hearts with a penalty winner in Sunday's 1-0 win in Paisley, and admitted he changed his mind at the last second.
It looked like calmness personified, but the Dutch striker saw keeper Trevor Carson going early, and instead struck the penalty into the bottom right corner.
And van Veen admits the win was huge for Motherwell, following a week of turmoil, starting on Thursday with their dismal Europa Conference League second qualifying round exit at the hands of Sligo Rovers.
