STEVEN GERRARD is encouraged by the unpredictability of his free-flowing Rangers forward line this term.

The Gers extended their advantage over Celtic in the Premiership title race to 11 points with a 4-0 win over Aberdeen on Sunday.

Ryan Kent and Kemar Roofe netted in the first half, while Jermain Defoe and Cedric Itten came off the bench at Ibrox as Scott Arfield and James Tavernier also scored.

And Gerrard is delighted with the attacking options that he has at his disposal after another incisive performance from the league leaders.

He said: "They are all important but today I was really interested to see the relationship between Alfredo (Morelos) and Kemar. To see how they played together.

"We saw it a few weeks ago with JD and Kemar, their understanding and relationship.

"It’s important that Alfredo gets that relationship with Kemar as well.

"It’s very difficult to play against because they can come short or go in behind, or come off the side as well. We have No.8s who can go beyond them.

"We want to give opposition teams as many problems as we can because at times in the past we have come unstuck by maybe playing in front of teams too much, being a little bit predictable and maybe not having enough answers. I’m really pleased how we are looking."
