I'm sure Messi and Mpappe dislike blocking Free kicks on the Ground. The Good news is that When they get the chance to score they will score to avoid having to block Free kick on the ground. Its very good psychology and it will force them to become attacking beasts. Its like you go to a mama put and are told to eat you must wash every bodies dishes, when it comes to your turn to eat you will over eat to make up for humiliation.
