In a tweet in August, Saif Rubie accused Liverpool of "mentally bullying and destroying the life" of Duncan, 18, who joined Fiorentina in September.

He also said Duncan was being kept by Liverpool against his will but the club described the allegations as unfounded.

Rubie was also ordered to complete an education programme and fined £10,000.

Duncan joined Liverpool from Manchester City in 2018 and scored 32 goals in all competitions for the club's under-18 side last season.

The England Under-19 international, who is also ex-Liverpool captain and current Rangers manager Steven Gerrard's cousin, was sold to Fiorentina for £1.8m.
