Martinez Emiliano the Argentina's goalkeeper is too good that he is capable of saving every shot coming to the net, this may be problem for Liverpool to win the match. Aston villa has quality goalkeeper that matters alot .
Lol, Martinez is definitely not going to be between the sticks tomorrow, WC finalists/winners get extra days off (10/12 days after the final i guess), but even if he was going to be in goal tomorrow it doesn't mean he wouldn't get beaten, i mean, he is a good goalkeeper no doubt about that, but i don't think he is anything close to world class, and even world class goalkeepers get beaten many times when they are left exposed.
Having said that, the best goalkeepers often keep for the best teams, and they concede fewer goals because they have a strong team/defense and they hold the ball more often than not, leaving them exposed only a few times of which they will save some and concede a few. But a goalkeeper in a small team would be exposed many times and will concede many goals no matter how good they are, if Martinez was to keep tomorrow, it won't stop Liverpool from scoring more than two goals, because they will definitely control the game, open up Villa and have many shots at their goal.
