I can counter that Messi has had a more stable system that can basically promote any amateur Barca manager seemlessly. As for best players, he currently has Iniesta, Saurez and Neymar. This is the highest concentration of attacking talent since the Galactico era. Contextually, one league trophy in the age of this dominant Barca team is probably not that bad. It doesn't compare to Kenya losing trophies to Leicester and lacklustre United teams
