Lisandro Lopez scored one goal and assisted two as Racing Club eased past Bolivar, while Robinho made his Atletico Mineiro bow.
Lisandro Lopez was on target as Racing Club opened its Copa Libertadores group stage campaign with a 4-1 demolition of Bolivar.
Former Argentina international striker Lopez, 32, scored the first goal of the match and assisted two others as Racing made light work of its Bolivian opponents in Group 3 on Wednesday. Lopez, back at his boyhood club after making his name at Porto and Lyon, latched on to Oscar Romero's well-weighted pass in the 11th minute before lobbing the ball over onrushing goalkeeper Romel Quinonez from the top of the penalty area.
