Aston Villa manager Martin O'Neill has refused to single out Zat Knight for criticism after his part in the 4-1 weekend slump against Manchester United.
O'Neill's men were carved apart by some enthralling forward play, however they were very much victims of their own downfall following a number of sloppy defensive errors.
Knight, who joined Villa in the summer for £3.5million from Fulham, was guilty of some lapses in concentration which cost his team-mates dear.
His place may well be under threat with likes of loan-signing Curtis Davies waiting in the wings.
O'Neill, though, has backed the 27-year-old centre-back to respond in a positive manner, and praised his displays since arriving at Villa Park.
"Everyone will come in for criticism at certain stages. I'm not going to go down the route of singling out any players," he said.
"Everyone has a responsibility, every time you step on the pitch. In every Premier League game you play, you have a chance of doing well or playing poorly.
"Overall I've been very pleased with Zat. He got into the side a week or 10 days before Curtis Davies arrived here and I've been impressed. I've been pleased with the efforts of a lot of the team."
