Ally McCoist has warned his Rangers players that he wants to see a greater hunger to score goals and punish teams after watching them book a place in the semi-finals of the Petrofac Training Cup with a 2-0 win at East Fife.

The Ibrox manager has a last-four meeting with Alloa Athletic at the Indodrill Stadium to look forward to thanks to contributions either side of the half-time interval from Jon Daly and Ian Black. However, he had hoped for another emphatic victory to follow up the 6-1 league win over Raith Rovers at the weekend and has made it clear that his players need to become more selfish as they endeavour to succeed in all four of the domestic competitions.

"We are through and that is the most important thing, but we could have won it a little more comfortably and been more clinical," said McCoist, who replaced his first-choice strikers, Kenny Miller and Kris Boyd, with Daly and Nicky Clark.

"It wouldn't be me if I didn't have a moan, but you want to score more goals and I said that to the lads after the game. It was an opportunity for strikers and midfielders to get on the scoresheet and get their goal tally up for the season. There has to be a real desire to go and score goals in every game and not just in big games. That has to exist at all times in the game and I would like to see a little more selfishness and desire to go and score."

Richard Foster became involved in an exchange with some supporters during the second half when on the main stand side of the field, but McCoist does not believe it was anything to become too concerned about. "I didn't see or hear anything," he said. "However, you will never win that battle, arguing with the fans. The irony is not lost on me. When they get a bit of stick back, the toys come right out of the pram. I will have a wee word if need be, but I wouldn't have thought that necessary."

Gary Naysmith, the East Fife manager, admitted he was satisfied with the performance of his team. "We could have done better at the second goal, but our energy levels were different class," he said.
