The Gers remained unbeaten in their European campaign this season after managing a 2-2 draw against Villarreal away from home on Thursday night.
The Rangers legend was impressed with the pass from Dorrans that almost fed in Scott Arfield to earn the Gers a win against Villarreal.
“Brilliant play from Dorrans,” said McCoist on BT Sport’s website. “Watch the vision here, with his left foot. that’s a sensational pass.”
The 31-year-old joined Rangers in 2017, signed by Pedro Caixinha, but was restricted to 20 starts last season with injury restricting his appearances.
He made his first appearance since May as a late substitute against the La Liga giants, and nearly made an instant impact with a superb pass.
Dorrans replaced full-back Borna Barisic on 85 minutes on Thursday, and the Scotland international split the Villarreal defence with a great run and pass that nearly resulted in a goal.
Dorrans is a fantastic player and he could be a key asset for Steven Gerrard’s side. His quality and experience will make Rangers a strong force in the Scottish Premiership this season.
