Officially the first signing of the post-Sir Alex Ferguson era, the tenacious right-back earned a dream move from Penarol after impressing on trial at United.
The Uruguay Under-20 international caught the Reds scouts' attention when representing his country in the qualifiers for the World Cup at that level in Turkey. A no-nonsense youngster who enjoys the challenge of defending, he performs with a combination of intelligence and aggression.
In a pretty unique situation, his entire trial was spent with the first-team squad and he impressed Sir Alex Ferguson and the players with his ability to adapt to what was a huge step up in class.
After jetting in to Manchester in June to sign his contract, he will aim to make his mark at Old Trafford and provide cover for first-choice Rafael after the move was authorised by incoming boss David Moyes.
