I don't understand much of these international games...
international games mostly had less 2.5 goals ,
you can try under 2.5 goals joca's picks for more save bet
last time i win under 2.5 goals bet on italy match versus croatia
international games also freaquently drawn, for this you can follow joca's premium picks.
International games with balanced teams and in decisive games have less than 2.5 goals most of the times.
Things are different in friendlies, or when one team is better than other(I mean better, not has more tradition or titles), or in non-decisive games.
Take for example the last WC, if you bet less than 2.5 during the stage you would lose most of your bets, but most of games in the elimination stage ended with less than 2.5 goals(with exceptions, like Nigeria vs France).
