Frank Lampard has been impressed with Hakim Ziyech's personality since joining Chelsea in a £37 million ($48m) move from Ajax, particularly relating to his 'inner confidence' and ability to connect with people.
Chelsea signed the 27-year-old in February and he joined up with the squad in July but his early career in west London has been disrupted by a twisted knee sustained in the club's only pre-season game away at Brighton.
Ziyech has since recovered and made his first start for the club in the 4-0 away win over Krasnodar in the Champions League.
