Steven Gerrard has backed Alfredo Morelos to keep his cool as he prepares to make his return to Celtic Park on Sunday.

The Light Blues' 28-goal striker collected his fifth red card of last season on his most recent visit to Parkhead back in March after he aimed an elbow at Hoops skipper Scott Brown.

This term, the Colombian has only been dismissed once and his manager saw signs during the Rangers' Boxing Day win over Killie - where Morelos climbed off the bench to score the winner - that show him the striker has learned his lesson.

Gerrard said: "I have got no doubt he will be ready to face this challenge at the weekend.

"He's in the best place he can be. His behaviour has massively improved again.

"When he came on again yesterday there were people trying to provoke him and he just rolled on with it. He was brilliant."

Morelos suffered fresh derby agony earlier this month as he blew a string of chances - including a second-half penalty - as Rangers failed to turn domination into victory in the Betfred Cup final.

But Gerrard has no doubt the 23-year-old will be ready to finally break his 11-game drought against Celtic this weekend.

He said: "The players will motivate themselves if they have anything about them. This is a place that should excite them. We won't do anything different for an Old Firm game.

"I thought Alfredo's all-round performance was really good. He created a lot of the chances for himself out of nothing.

"He's just got to go do exactly the same thing but try and take the big moments in the game. If he does it will give us a better chance of winning. His inner resolve is an area of him that I don't think you ever have to worry about.

"He's in love with football. He doesn't like missing one minute of training. He doesn't like being a sub or coming off. He motivates himself every time he sees a ball."
