You aren't making any counterargument.Diego won trophies with Boca and Barça, but the most remarkable was winning it all with Argentina in '86 (he played well in the final, serving the assist for Burruchaga to win the game), then reaching the finals with an very average team in '90 and winning scudettos with Napoli. Those teams were never supposed to go that far.
The Spanish NT that championed in three consecutive tournies from 2008 Euro - 2010 Mundial - 2012 Euro is widely considered the best ever. It was based on Barcelona's players and tiki-taka style of play. At the same time Messi couldn't win trophies with Argentina. While I wouldn't call second place a failure, the best should have made the difference in 4 finals or while playing CA at home.
