Dundee United boss Gordon Chisholm believes that the loss to injury of Collin Samuel was the turning point as his side lost 3-0 away to Rangers.
"It was a massive blow losing Collin Samuel as we don't have anyone else with his pace and he helped pin them in their own half," he said.
"I thought we had the upper hand in the first half, but not for the first time we failed to take our chances.
"And we lost three goals from crosses and let them in too easily."
