At international level, he represented the Uruguay national football team at the 1997 FIFA Confederations Cup, at the 2002 FIFA World Cup, and at the 2004 Copa América. Montero has been described as “skilful on the ball and calm under pressure”, and a “wonderfully talented and intelligent footballer”. His international reputation is one of a man who was “fearsome, immovable and essential, in a back line that conquered Italy and Europe”. A versatile defender, he was capable of playing in the centre or on the left, and was known for his strength, consistency, leadership and organisational skills. Montero also stood out during his career due to his aerial ability, timing, technical ability, and distribution. A combative, tenacious, complete, and talented defender, he was also frequently criticised for his aggression and hard tackling throughout his career, as well as his knack for picking up unnecessary bookings. He holds the record for the most red cards received by a player in Serie A history, being sent off 16 times, and was sent off a total of 21 times throughout his career. In 2007, The Times placed him at number 39 in their list of the 50 hardest footballers in history.
