Former Ajax manager de Boer has made it known that he is keen on taking over in L4 after six years in charge of the Eredivisie side.
But Van Der Sar, who worked with de Boer at Ajax, claims that, with such a high number of excellent managers taking charge in next season’s Barclays Premier League, the competition could be tough to contend with for de Boer.
“When you look at the names like (Jurgen) Klopp, (Pep) Guardiola, (Jose) Mourinho, (Arsene) Wenger then it will be a very tough season for him to do well at Everton.
“I would like to see him go in there because it would be very interesting.
“He does have a way of playing that is very interesting for England.”
“He would be a very good manager, but the question is how (would he do) with the competition from the other teams.”
Ex-Netherland star de Boer has not been contacted by the Blues as of yet, but the 46-year-old has made it known that he is interested in the vacant managerial post on Merseyside.
Twin brother Ronald has spoken of his de Boer’s keen-ness in becoming the next Toffees boss, but it remains to be seen whether the former Barcelona and Glasgow Rangers man will take charge of Everton next season.
Ex-Manchester City manager Manuel Pellegrini, Sevilla head coach Unai Emery and former Blues boss David Moyes are also vying for the position of Everton’s next manager after the sacking of Roberto Martinez two weeks ago.
