Daily Mail in sensationalising football manager's quote shocker.
If you read the quote, all he actually says is "‘I think you should be respectful, You have to be ruthless as a manager when it comes to picking teams. If you’re not winning, you won’t be in a job. That’s where the ruthlessness comes from".
It was clear from his post-match interview after the Coventry game at the end of last season that he knew Cortese was looking to replace him. He could have looked for another job or walked in the summer, but he stuck around and waited to be sacked instead.
