McAllister told Rangers TV: "We have two centre-halves with a big physical presence and they've had opportunities. Even if you ask them, I think they'd be looking to score a few more goals.

"If you can add defenders onto the scoresheet, it's such a big thing."

McAllister believes Worrall has been outstanding in recent weeks.

The England Under-21 international gifted Kilmarnock a goal in a 2-1 defeat immediately after the winter break but he has helped Rangers keep seven clean sheets in his subsequent nine appearances.

McAllister said: "In the last four or five games he has been excellent.

"I'm unaware of the criticism he has been getting. We just focus on how he trains and how he prepares for games, and he's been excellent.

"He has been a particular stand-out in the last three or four games, shown a bravery to get on the ball and pass the ball, and it was nice to see him get the goal."
