The Dutchman was sacked yesterday following a poor run of form that had yielded just two wins in 13 games, left the Blues in the bottom three of the Premier League and almost eliminated from the Europa League with just one point from three group matches.
In a statement, Koeman thanked the board, players and fans:
I would like to place on record my thanks to the players and staff for all their work and commitment during my 16 months as Everton manager.
I would like to thank Bill Kenwright, Farhad Moshiri and the Everton Board for the opportunity to have managed a great club, and to the fans as well for their passionate support for the club.
Naturally, I am disappointed at this moment, but I wish the team good luck in the future.
