Chelsea are watching Ajax star Hakim Ziyech.
Calciomercato.it says Maurizio Sarri's side have their 'eyes' set on the Morocco international.
Ziyech has notched up 15 goals and provided 13 assists in all competitions for Ajax, including one against Real Madrid in the Champions League.
Ajax signed the winger, 25, from Twente in 2016 for £11million but is now valued at upwards of £35m.
However, it remains to be seen whether Ajax, who have already lost Frenkie de Jong to Barcelona for an initial £65m, are prepare to entertain offers.
