Is not just Vidal (great effort) but the balance of the team with De Jong in his right position, Dembele instead of Griezmann (who does not feel comfortable on the left); Messi and Suarez with more space.
It's a tactical issue: our players, if they are put in a condition of doing what they can do better, are strong (Suarez is the perfect example). And you carry on insulting them...
