Cook reckons Sparky's days are numbered.
The 30-year-old, now at Leyton Orient, said: "I don't think Tony Fernandes will muck about. When it was Neil Warnock's time to go it was 'see you later' - he didn't hold back.
"Just because it's Mark Hughes and a big name it means nothing.
"If the next seven games are like the first seven, then the club would have four points and nobody has lasted that.
"Harry Redknapp would be a great man to get the job. When a manager like that is available, then I can't see him saying no."
