Masters mistake was taking the job and becoming a patsy for the red top, he never had anything about him to do this job.Let's not forget, when people think they are untouchable they make mistakes. I wouldn't put it past people like Gill and Parry to put down in writing to the PL things they shouldn't.
And Masters is not an impressive man. Put him under increasing pressure and watch him break. He will make mistakes as the end-game gets closer, I am sure.
