Roberto Néstor Sensini (born 12 October 1966 in Arroyo Seco, Santa Fe) is an Argentine defender for Italian side Udinese.
His professional playing career started in 1986 for Newell's Old Boys; he then relocated in Italy in 1990, starting his adventure in the European country which still goes on today just for Udinese. He played 5 seasons in his first adventure for the bianconeri of Friuli, before to move to Parma in 1993; he stayed in Parma continuously till 2002, except one season (1999/2000) for S.S. Lazio, where he won his one and only scudetto. During his gialloblu period, Sensini won two UEFA Cups and two Italian Cups with the team. After his long stay in Emilia, Sensini then went back to Udinese in 2002, and he still plays for his first (and probably last) Italian team. In 2005, he has been one of the main protagonists of the surprising qualification of Udinese in the UEFA Champions League.
Sensini is one of the oldest players of the 2005/2006 Serie A, and holds the record as the oldest foreign player to score a goal in first division with 39 years, two months and 26 days. With over 380 matches in first division, he is considered as one of the most experienced defenders of the Italian league, and is often nicknamed nonno (grandfather) by Italian sports journalists.
"Boquita" Sensini debutted for his national team in 1987, and until his last match in 2003 gained more than 60 caps, including the 1994, 1998 and 2002 World Cups.
