Basel tried it out against Schalke in the 2013 Champions League only for the linesman to make an epic blunder and not spot the offside.
So when such crucial decisions go against you,teams generally are very averse to taking such a risk. Luis Enrique took a chance and it came off perfectly. Enrique except for the Messi issue which nobody really knows what happened has been his own man refusing to bow to pressure from either the fans or the board. From moving Messi out wide to dropping Xavi completely from the big games,Enrique has taken some tough decisions which have payed off well so far for Barcelona.
