Everton boss Roberto Martinez is coming under increasing pressure at Goodison Park.

The Mail on Sunday says in a shock development it is understood Martinez is suddenly under immense pressure at Everton in the wake of Neil Warnock's dismissal at Crystal Palace.

The 66-year-old Yorkshireman became the first Premier League managerial casualty of the season on Saturday.

The man who is being lined to replace Martinez as new Goodison Park boss is former England manager Steve McClaren, currently in charge at Derby County.
