Rules
The finals will be played over two legs; home and away. The team that accumulates the most points —two for a win, one for a draw, zero for a loss— after the two legs will be crowned the champion. If the two teams are tied on points after the second leg, a playoff in a neutral venue will become the next tie-breaker. Goal difference is going to be used as a last resort.
