In 2005, he was one of the most consistent performers in Udinese's surprise qualification for the UEFA Champions League. Sensini was one of the oldest players of the 2005–06 Serie A, holding even the record as the oldest foreign player to score a goal in first division, at the age of 39 years, two months and 26 days. With over 380 matches at the top level, he was considered as one of the most experienced defenders of the Italian league, and often nicknamed "nonno" (grandfather) by Italian sports journalists. He retired at the end of the season.
