Koeman had a previous disastrous spell in charge of Valencia.
"When Koeman arrived in Valencia I asked a friend of mine who saw all the Ajax matches and told me that he was able to take advantage of a project that is already rolling and give it continuity, but that he was unable to create a new project," recalled Canizares.
"He defined him perfectly. Everton signed several important players who arrived for a lot of money and once again have not been able to create a project ... he is not a coach who knows how to create a project, hopefully he'll learn.
"He came to Valencia to restore a team which was a little broken and broke it even more."
