Former Borussia Dortmund striker Lucas Barrios made his return for Argentinos Juniors on Sunday, which also saw Belgrano get an away win over relegation-threatened Olimpo, and two Big Five clubs lose. Racing went down to Unión thanks to a golazo from Diego Zabala, and River Plate – in a match delayed by a bomb threat – lost 1-0 away to Huracán in another poor performance.
