The Argentine hasn't missed one since September
The penalty kicks is the only pending subject for Barça this season. The team have missed 8 out of 19 tries and the best trident in the world (Messi, Suárez, Neymar) found this curse in the probably easiest action in soccer.
In La Liga, Luis Suárez had missed the last two penalties against Sporting and Rayo Vallecano. Messi had let him kick them so he could keep fighting to become La Liga's top scorer. This Sunday, Barça was able to score from the penalty point again and Messi did it.
As can be seen on this images by Cuatro TV, before the penalty, Suárez told Messi to kick the penalty. The Argentine understood immediately and kicked it with calm, sending the ball in the middle of the goal after the goalkeeper jumped.
