At the main menu press Up, X, X, Right, Right, Y, Y, Y.
Beat all the classic matches and you will unlock all time. Best with all the greatest players in it.
To have an easy win, pass the ball back to the goalkeeper, then hold the Left trigger and Y, then release Y and the ball will go very far. Do this towards the opponents goal and then get a forward to run on to it then dodge the keeper and score.
