I traveled to the mountains of Mendoza and found the Argentine football guru - Leo Alvarez. 

We discussed Argenitna's World Cup squad. Who's in and Who's out. Their path to the final. 

The man who took the job when no one else wanted it. Lionel Scaloni, and what the team he has built in the last 3 years. 

And the age old question. Who is the greatest Argentine of them all? Messi or Maradona?
