Teenage striker Alexandre Pato scored one goal and set up another to help Libertadores Cup champion Internacional to a 3-0 win over Emelec on Wednesday.

Inter picked up its first points in Group Four while Uruguayans Nacional, the side that beat it in its opener last week, drew 1-1 at Velez Sarsfield thanks to a defensive blunder from its Argentine opponents.

After helping Inter win the Club World Cup in Japan at the end of last year, Alexandre, nicknamed "The Duck," was making his first appearance at its Beira-Rio stadium in Porto Alegre and he treated the home fans to an inspired display.

The Brazilians went ahead in the 26th minute with a 20-meter volley by midfielder Perdigao before Alexandre set up Internacional's second goal in the 56th minute, rounding goalkeeper Marcelo Elizaga and chipping the ball into the area for defender Indio to head home.

The best was still to come and 11 minutes later, he collected the ball outside the penalty area, jinked his way past his marker and found the far corner of the net with a low shot.

He was substituted shortly afterwards, much to the relief of the Ecuadorean visitors.

The win left Inter third in the group with three points while Emelec, still pointless, is bottom.

Three-time former champion Nacional leads with four points from two games, ahead of Velez on goal difference, after its valuable draw in Buenos Aires.

Velez, led by Mexico's World Cup coach Ricardo La Volpe, broke the deadlock in the 43rd minute when Damian Escudero beat two defenders and scored with a low shot from 25 meters.

Nacional equalized three minutes after the break when Velez defender Hernan Pellerano's back pass was intercepted by Diego Vera, who rounded Gaston Sessa to score.

With the match being played in humid conditions, La Volpe ditched his trademark jacket, jeans and bright tie for a lightweight cotton white shirt with blue streaks and matching white shoes.

Sao Paulo, last year's runner-up, beat Peruvian champion Alianza Lima 4-0 at home to pick up its first win in Group Two.

Alex Silva scored twice for the Brazilians while Leandro and Junior shared the other goals as they capitalized on slack marking by the visitors.

Sao Paulo has four points from two games, followed by Audax Italiano on one and pointless Alianza.

Mexico's Necaxa leads with maximum six points after beating Audax 2-0 in Aguascalientes.

Brazilian striker Kleber Boas put Necaxa ahead in the eighth minute after the Chileans lost possession in defense.

Aaron Padilla hooked in the second in the 70th minute when Horacio Cervantes headed back across goal from a corner.
