With two games to go the domestic league is wide open, with six teams within six points of each other. But however important it is to Argentine football fans for their team to win the championship, each would gladly lose the title to their arch rivals on the last day of the season 20 times over in exchange for a Copa Libertadores in their dusty cabinets.
The hopes for the Copa coming to Argentina are now in Boca Juniors' hands. And if a team can be convincing while still drawing at home, then that was Boca.
On a bitterly cold night (OK, it was 5C which is bitterly cold for Argentina) against, Brazilian side, Fluminense - mostly wearing gloves - Boca maintained a relentless attack on goal throughout a thrilling match.
When Riquleme scored an 11th minute goal from a lovely flowing build up, it looked as though the night was Boca's. The crowd, packed into Racing's impressive stadium - built for the 1978 World Cup - believed the night was theirs. Fluminese's equaliser three minutes later did little to dampen the party atmosphere as probably the most fluid performance from Boca all season constantly threatened another goal.
Riquleme's second, a free kick, came just after half time and the erstwhile mild mannered number 10 danced around the stadium and kissed the ball before placing it on the centre spot.
But against the flow of play, on the counter-attack, Fluminese's lofty Migliore hit one from outside the penalty area. It slipped through the goalkeeper's hands giving the Brazilian's a potentially crucial away goal.
Boca now have to go Rio de Janeiro in a week with Argentina's hopes weighing down on their shoulders.
