Roberto Néstor Sensini (born 12 October 1966) is an Argentine football manager and former player, who played as a centre-back or defensive midfielder.

His professional playing career started in 1986 for Newell's Old Boys; where he won his first title before relocating to Italy in 1989, joining Udinese alongside compatriot Abel Balbo.

In the 1990 FIFA World Cup Final Sensini conceded the disputed penalty kick from which West Germany scored their winning goal.

[9][10][11][12] Although he primarily excelled defensively as a ball winner, due to his marking and tackling ability, as well as his tough, aggressive, and physical playing style, he was also a player with good technique, who was capable of making attacking runs and contributing offensively for his team with occasional goals.

[13][14][15][16][17] On 10 February 2006, after the dismissal of Serse Cosmi, Sensini ended his playing career and was appointed Udinese's new manager.
