Celtic icon Kenny Dalglish reckons Rangers boss Steven Gerrard has a mammoth task on his hands to pick which striker should play up front at Ibrox this Sunday.

Gers welcome their fierce rivals across the city this weekend and Sir Kenny believes the hardest decision for Gerrard will be who to play.

Jermain Defoe and Alfredo Morelos have both been in scintillating form with the former netting six in nine already and the latter nine in ten.

Colombian Morelos may well be in slightly better form statistically, but Defoe's link-up play and experience could be vital for his side as they look to beat Neil Lennon's troops.

There's also the small matter of the fact that El Buffalo is yet to score in an Old Firm game since he signed on with the Light Blues.

Steven Gerrard has been rotating the pair this season so far, but Dalglish insists he's never had a bigger call to make.

Speaking in his Sunday Post column, Dalglish said: "What will give Steven Gerrard confidence is that his players have been right on it in the early stages of the season, and there is healthy competition for places.

“Nobody at Ibrox can take a place in the starting line-up for granted. That is especially true for the striker role. Right now, you could toss a coin between Alfredo Morelos and Jermain Defoe as they are both in really good form.

“At this stage, I don’t think Steven will have chosen which of them will start against Celtic.

“If one of them really shines in the next five days, they will secure a slot from the first whistle next Sunday.

“Jermain is highly experienced and, as well as being a fabulous finisher, he holds the ball up well. He is comfortable on either foot, and brings his team-mates into play. Alfredo is not quite as polished in terms of link-up play outside the box.

"But the Colombian is first-class in front of goal, and uses his physicality well against opposition defenders. His disciplinary record has been good this season after his five red cards in the previous campaign.

"But one swallow doesn’t make a summer, and question marks remain. There is no doubt Celtic players will try to wind him up, and get a wee nibble at him here and there. That’s a part of the game.

"It’s up to Alfredo not to rise to the bait. It is solely his responsibility to behave. But I’m sure every other team in the past few weeks have tried to niggle him and get him to retaliate in certain situations, and he hasn’t risen to it.

"That’s a sign of him maturing and learning his lesson. But the game against Celtic will be the toughest test of all for him.

"So who to play up top against Celtic is the toughest decision of the lot for Steven. He knows that. Big calls are usually the difference between winning or not. Make no mistake, this particular call is massive."
