Ajax coach Frank de Boer isn't surprised by sudden transfer interest for youngster Anwar El Ghazi.
De Telegraaf says Atletico Madrid, Chelsea and Bayern Munich have had the 20 year-old watched in international action for the Holland U21s this year.
"Anwar is a great professional who works hard to become stronger day after day," said De Boer yesterday.
El Ghazi has impressed this season, scoring ten goals and making eight assists in 42 appearances for De Boer's first team.
The attacker is tied to Ajax until 2019.
