The Spaniard offered great hope during his first season in charge at Goodison Park, guiding the Toffees to their highest finish in the Premier League, fifth place, since the 2009/09 campaign.
But the Merseysiders failed to build upon that during Martinez’s second season, slumping down to eleventh place.
And a heavy 3-0 defeat to Sunderland yesterday evening mathematically ensured they will finish in the bottom half for the second season in a row – the first time they’ve done so for over a decade.
Pressure for the board to take action has gradually built throughout the campaign and particularly since Everton’s sudden slump in form in March.
The Toffees had previously won six in eight across all competitions, but are now amid a run of just one victory and six defeats in their last ten games. The Goodison hierarchy have felt compelled to respond by relieving Martinez of his duties.
Everton Football Club regrets to announce that Roberto Martinez has left his position as First Team Manager with immediate effect.
