Lets start off with Jonathan Bottinelli.
Bottinelli is 23 years old, a defender for Argentinian side San Lorenzo. Bottinelli has also been called up for the Argentina international squad when Martin Demichelis was forced to serve a ban. In 5 seasons at San Lorenzo, Bottinelli had amassed 116 caps with 9 goals for San Lorenzo. Seems very good for a youngster. Only 23 years old and he obviously has to have a fair amount of skill if he's going to be called up to Argentina squad which is currently ranked 6th in the world but was ranked as high as 1st only a month ago.
