Scenario 1: If Boca wins by 4 goals or more, they advances no matter what the result of the Atlas/Colo Colo game is Scenario 2: If Colo Colo defeats Atlas, the difference by which Colo Colo wins and the difference by which Boca wins must equal 5. Therefore, if Colo Colo wins by 1 goal, Boca must win by 4. If Colo Colo wins by 2 goals, Boca must win by 3 etc etc Scenarion 3: If Colo Colo and Atlas draw, Boca will have to win by 3 goals. If Boca wins by 2 goals, they have to score more goals in their victory than Colo Colo does in their draw (because if goal differential is tied, it goes to who scored the most goals). Scenario 4: The easiest scenario. If Atlas defeats Colo Colo, Boca just needs to win (don't have to worry about goal differential or anything). If Boca loses or draws, they are out of the competition. VAMOS BOCA CARAJ0! SI SE PUEDE! El ano pasado paso el mismo y ganamos sin dejando dudas contra Bolivar con el 7-0.
