No. If the team had played poorly or if certain individuals had failed to give their all, then Neil would be justified in changing his side for the Dundee match.
But his team played well, very well in the first half, and just failed to take their chances. It happens in football from time to time. There is no need to press the panic button.
Gary Hooper should have put the game out of sight if he had buried one of the chances which fell to him in the first half. He didn't. But it would be foolish to discard such a dangerous player on the evidence of one match."
