Guarani continued their dominant start to the Clausura of the Division Profesional, thrashing a hapless Libertad 5-1 on Sunday.
Guarani have been the form side of the competition so far this season but faced a stern test against a Libertad side who went into the round a game away from their top-of-the-table hosts.
In a frenetic start to the match between the cross-town rivals, Antonio Bareiro gave Libertad an instant lead in the opening minute before Luis Gonzalez levelled the scores just two minutes later.
Fernando Fernandez then made it 2-1 to Guarani in the 12th minute with Luis Gonzalez grabbing his second from the spot soon afterwards to put the home side well on top.
Two second-half goals saw Fernandez complete his hat-trick as Guarani romped home, ensuring they moved three points clear at the summit of the table.
