"Frank has already denied Liverpool and Tottenham," he told talkSPORT. "Tottenham wanted to take him in January but Frank said no.
"He also said no to Liverpool last year. He thought he was still not ready and wanted to learn more.
"Now he's ready though. We’ll have to wait and see [what offers he gets].
"It's important for Frank to get the right club otherwise he won't leave Ajax. He's very happy there."
De Boer confirmed his interest in someday taking charge of either club in February, while professing his happiness to remain at Ajax for the time being, though Sherwood took umbrage at his admission.
