Rangers manager Ally McCoist has questioned his team's attitude after their shock 1-0 defeat away at Kilmarnock.
Manuel Pascali's goal means that the Gers' lead at the top of the SPL has now been cut to four points.
"I would question the players' tempo and their attitude to go and win it," McCoist told the club's official website.
"We didn't play the game at a high enough tempo and we didn't show enough urgency to earn the three points.
"I believe for us to play at our best we have to play quicker and not give people time on the ball."
The SPL champions host Dunfermline at Ibrox next Saturday.
