On 200 1, fabiani was recruited into the national youth team to prepare for the 2003 South American Youth Championship. In 2002, fabiani's performance in the second team of Lanus attracted Feyenoord's attention. However, due to the cruciate ligament injury accumulated for more than two years, 19-year-old fabiani finally failed the physical examination and lost the opportunity to transfer to Feyenoord.

During the 2002 World Cup, fabiani was selected as a sparring partner of the national team. During this period, he collected many photos of aimar, Ayala, Buddy and others, and the most precious one was a Simone jersey signed by all the players of the national team.
