The highly rated 17-year-old full back completed his move from Brescia Calcio on a season long loan deal just in time for transfer deadline day however the Hammers could only recently announce the deal once the player had received international clearance.
Speaking to the official site for the first time he said, “It is fantastic to be here, it is like a dream.
“I am very happy to be in London. I am privileged to train under Gianfranco Zola as he is one of my idols.
“I like to attack as a full-back and I like to score goals but first my main aim is to be in the first-team squad and to do well for the club."
Ferrari will feature in the reserves game against Birmingham on Tuesday evening.
