However, Belgian pundit Peter Vandenbempt has questioned De Boer's suitability.
He told Sporza: "De Boer was the top candidate at Club Brugge last summer to follow Michel Preud'homme. They were willing to wait a long time, but felt that De Boer only wanted to come if he could not find another job.
"He had put his eggs in the basket of the Premier League, which does not seem to be a good basis to get started with a club like Anderlecht.
"If he is a choice for Anderlecht because there is nothing else, I do not know if that is a good choice."
