GRAEME MURTY is confident a fired-up Alfredo Morelos can prove a point and get back on the goal trail against Celtic.

The 21-year-old spurned a series of chances in the Scottish Cup win over Falkirk at the weekend as Jason Cummings hit a hat-trick in a 4-1 victory.

Morelos is set to lead the Gers attack when Murty’s side host their Old Firm rivals in a huge Premiership encounter on Sunday.

And the Ibrox boss reckons his star striker will be as determined as ever to get his name on the scoresheet once again and fire the Light Blues to derby success.

He said: “He’s a centre-forward and centre-forwards who don’t score goals are not happy animals, they are just not.

“He had some good opportunities but I have always said that he is going to miss chances and because he keeps on getting in there we are going to create him chances.

“We just need to get his ratio up. I have said that before and I said that when he was scoring.

“We can get his ratio up, we can get him sharper, we can get him more clinical.

“I think the frustration in him is that he is just desperate to score and desperate to do well, which is a good thing for me.

“I don’t think there is anything wrong with a centre-forward possibly going into a big, big game with a bit of a chip on his shoulder and a point to prove.”

Morelos has become an integral part of the Rangers side this term following his move from HJK Helsinki last summer.

The Ibrox board rejected a handful of multi-million pound bids for the Colombian during the January transfer window.

And boss Murty has no doubt Morelos will continue to go from strength to strength as he looks to add to his 17 strikes for the Gers in the coming weeks.

He told RangersTV: “Give him the opportunity to get that out of his head and free his mind up so that if he is faced with a one-on-one, he is confident and bright and he goes and sticks it away.

“Also similarly that he doesn’t get frustrated in someone doesn’t lay him in or pass him the chance.

“He just keeps on going, remains positive in his movement and his positive in his mindset and I think that is an important part.

“We have to remember he is still only young, he is still learning and he has still got lots and lots of improvement to do.

“He is still at the top end of the scoring charts, albeit he could be further ahead by now.”
