Transfer expert Fabrizio Romano reports Chelsea will be one of several clubs in contention to sign Nkunku from RB Leipzig next summer.
The Blues are set to throw their hat into the ring for the highly-rated France international forward, who won the Bundesliga Player of the Year award last season.
Nkunku hit 35 goals and registered 20 assists in all competitions last term and his numbers were among the best in world football.
In June, the versatile forward put pen to paper on a new two-year contract extension with the Bundesliga club that will keep him with Leipzig until 2026.
However, Romano is anticipating an auction next summer when Nkunku could move onto pastures new.
