The key will be in the balloon and in the spaces, those that the footballers of the Seville FC can generate during all the meeting in his research to cancel the characteristics of the FC Barcelona this Sunday in the Pizjuán. "To level of selection, the formula to brake to Messi that used was to have the ball so that it do not arrive him to him", said Jorge Sampaoli.

The Argentinian technician was able to cancel entirely to the ten in the final of the Glass America 2015, when Argentina and Chile empataron to zero and finish carrying the trophy, these last, with a batch of penaltis dramatic. It was an authentic cage in which they put to the rosarino thanks to a rosary of defensive helps and of several players that turnaron to manacle to Leo.

But the FC Barcelona is not Argentina and the "albi" does not have the resources (futbolísticos and humans) of which the culés have. Argentina did not have to Neymar to resort to this when Lionel was overwhelmed and hovered by his rivals.

The key will be in the Brazilian, in his way to assume once and for all his paper of leading player and to throw him a hand to his fellow. If close to Messi already is difficult, impossible will be to do it with the two. Byell or "Ney" will have to appear like the best key for the "cage" that will mount him to his mate.
