Redan, 18, left Ajax in his native Holland for West London in the summer of 2017, but German publication Sport Bild, as cited by Sport Witness, say he sees ‘no chance’ of breaking into Maurizio Sarri’s side.
The Toffees are one of a number of English clubs supposedly interested in Redan, who can play out wide, as an attacking midfielder or up front, with West Ham United and Leicester City also reported to be watching him.
Meanwhile, across Europe, German outfit Borussia Monchengladbach and Italian duo AC Milan and AS Roma are also linked with Redan.
In 28 appearances for Chelsea’s under-18s and under-23s, Redan has registered 11 goals and two assists, but is yet to make his first team bow.
He is said to be available for a fee of roughly £8.5 million.
