The Colombian striker has been in red hot form since signing on at Ibrox from HJK Helsinki in the summer.
He had seven goals in eight games going into this evening’s trip to Firhill and has now made it eight in nine matches with a superb goal to make it 1-0 in the first half.
Receiving a pass from Ryan Jack on the right of the Thistle penalty box, Morelos needed just one touch to set himself and he produced an emphatic shot beyond Ryan Scully and into the back of the net:
That is a quality finish from Morelos – and one which will continue to add to the hype around the striker.
It also sets Rangers up to get three points and their third victory on the trot after wins over Ross County and Dundee in the league over recent weeks.
