According to TA reporter David Ornstein, Chelsea have made contact with Ajax to express an interest in signing attacking midfielder Mohammed Kudus.
The Premier League club are yet to submit an offer to their Dutch counterparts, but initial dialogue has taken place.
Kudus is among a number of options Chelsea are considering and an agreement with the Ghana international on personal terms is close.
Kudus, under contract to Ajax until 2025, rejected a one-year extension in April and is keen to leave the Johan Cruyff Arena.
Kudus, 22 years old, has scored 11 goals and assisted 3 times for Ajax last season in 30 appearances.
