Tevez (21), Messi (19) need to warm the bench and let the elders show them the ropes. Argentina did great without them in the qualifiers against brazil and ecuador. In the second half may be around 60-70mins they need to be inserted to tear apart the German defense. By that time, I recon Germans will be playing with 10 men.
