Brian Laudrup insists the attitude of Alfredo Morelos is vital to whether Rangers can beat Celtic on Saturday.
The Ibrox legend believes the Colombian can be the matchwinner for Steven Gerrard's men at Parkhead, as long as he forgets about his barren run against the Hoops.
The 24-year-old is yet to score in 11 games against Celtic and has had some high-profile misses, including a penalty in the Betfred Cup Final defeat last season.
But Laudrup still reckons he can be vital to Rangers in a tactical battle if he focuses on the job at hand, even if it means being more unselfish than usual in front of goal.
The Dane has pinpointed the battle with Shane Duffy at the heart of the Celtic defence as a key part of the game and urged Morelos to create space for the likes of Ryan Kent.
In his Daily Mail column, he said: "Alfredo Morelos v Shane Duffy is one that promises to be box-office material. A physical match-up taken to the limit.
"Morelos has a long trip back from international duty with Colombia but, if he starts, he will inevitably be the focus of a lot of attention.
"We all know his temper is an aspect he sometimes struggles to control, although we haven’t seen as much of that this season.
"Duffy is an old-school centre back. He knows his tricks, without offending him. He is superb in the air both defensively and when attacking set-pieces - which he has already shown - but he lacks a bit of pace in certain area.
"If Morelos can drop deep and drag him out of position, there could be space to exploit in behind Celtic’s back three. Ryan Kent has already shown he can do that.
"Scott Arfield is another whose late runs are very difficult to track. These are weapons that could hurt Celtic if their defenders are not at the very top of their concentration.
"Of course, the fact Morelos has never scored in an Old Firm match is part of the narrative here. It must be incredibly annoying in his mind, but I think the Rangers management team will try everything in their power to make him focus on his performance first."
