Only Boca Juniors of the Big Five, which also includes River Plate, Independiente, Racing Club and San Lorenzo, have won a league crown in the last four-and-a-half seasons, while the likes of Banfield and Arsenal clinched their first.
River, back in the top flight this year after a traumatic first relegation, and arch-rivals Boca changed coaches at the end of 2012 in a perceptible shift towards attack.
Boca fans chanted his name and jeered Julio Cesar Falcioni at the end of their final match of the championship last weekend, a 2-1 win over Godoy Cruz, forcing the club not to renew the unpopular coach's contract.
Life was much harder for their Avellaneda 'barrio' enemies Independiente, fighting against what would be a first relegation and the ire of their barra brava hooligan fans who have been denied customary favours by club president Javier Cantero.
After Sunday's 2-2 draw at home to Colon, the players were ushered out of a back door to avoid angry fans inside the club.
"It's a complicated situation. I think that to leave through this door is wrong... we need a good pre-season, we know it's difficult," Morel told reporters.
"We wanted to finish [the Inicial] outside the relegation [zone]... the fans want to see the team winning. We don't manage it and they go away angry. We gave everything against Colon but didn't get the win."
Coach Americo Gallego, the last man to lead Independiente to a league title in 2002 and who returned in September, said: "We are very nervous and the fans pressure us more."
San Lorenzo have shaken off their cautious approach under former Spain striker Juan Antonio Pizzi, who took over in October, and escaped from the bottom three in the relegation standings, a table of teams' average points over three seasons.
