Hakimi spent the last two seasons with Bundesliga giants Borussia Dortmund but surprised many by deciding not to return to the Santiago Bernabeu upon the expiration of his loan.
The Moroccan, who made his Los Blancos first-team debut under Zinedine Zidane in 2018, has since revealed that Antonio Conte's style is what attracted him to the San Siro.
"I chose Inter because I think the coach's style is particularly suited to my way of playing and I can be of real help to this team," the full-back said in Inter's Q&A on social media.
"We'll try to achieve great results and certainly aim to win the Scudetto.
"Conte is a great coach, with a very competitive spirit. He has this extraordinary passion for football and transmits that to his players, fans, and everyone around the club. His motivation allows the side to be fired up for every game.
"I already played 3-5-2 at Borussia Dortmund. When the offer came, I thought this was a great opportunity for me to grow, as the fans here experience football in such a special way. I have joined a great club."
