Actually after a bit more digging I found this as well:
single player or a joint team uses the World Cup team of their choice to try to defeat another in a timed period. The team moves on to the next team if they were victorious. The game has 7 levels, you can choose your next rival, but the last one is always the same. To make it easier, you can use special shoots spending one or more units. You get extra units when you win matches; or you can buy more by inserting coin(s) and pressing the 1 player button - if you are using that player.
Tips for special shoots: - The best shoot is the hyper shoot, it's unstoppable. The best moments to use that shoot are at the beginning of the final or when time is almost up and you need a goal to win. - If you use the super shoot, the goalkeeper can avoid the goal -but sometimes he can't and ends inside the net

or scores an own goal-. - To show the menu with the special shoots, push 'button 3' when you see 'Push C Button' -if you haven't done at the beginning of the match-. You choose one pussing 'button 3'. - To activate the shoot use the 'button 3'. (to activate hyper and super shoot you must do that twice, the first time you pass tha ball to another player and the second time activates the shoot).

Sometimes, the player you chose when you started to play can make super shoots. It happens only once per match and when time left is less than 45 seconds. This is random, but it seems this can happen when you pass the ball to that player using Button 2.
Tip 1: You can make a free hyper shoot *only* when the result is a draw and time left is 10 seconds or less. To activate it, you must pass the ball to the captain using button 2.
Tip 2: You can make a free super shoot when time left is 30 seconds or less. To activate it, you must pass the ball to the captain using button 2. But this time the result doesn't mind (You can do it when you are 0-0, winning, losing,....).
