In the summer of 2000, Farinós caught the attention of Serie A's Inter Milan, where he would spend five years (with a Villarreal CF loan in between) without much success. He was out of action for 15 months due to injury, and was only able to pitch in ten league games as his team lost the 2001–02 league title in the last matchday; he did manage, however, to score in a 6–0 home rout of Reggina Calcio on 22 November 2003, under head coach Alberto Zaccheroni.
