Gustavo Bou struck a hat-trick as Racing Club started their Copa Libertadores campaign with a 5-0 thrashing of Deportivo Tachira on Tuesday.
Gustavo Bou and Diego Milito led the charge as Racing Club crushed Deportivo Tachira 5-0 on the opening day of the Copa Libertadores' group stage.
Bou struck a hat-trick and set up Racing's opening goal away to Tachira, while Milito finished the match with a goal and two assists, as the Argentinian Primera Division side powered their way to victory in Venezuela.
In Racing's first Copa Libertadores match since 2003, Luciano Lollo opened the scoring in the 21st minute with a flick from Bou's free-kick.
It was 2-0 by half-time with Bou playing a one-two with Milito before crashing his volley past Tachira goalkeeper Alan Liebeskind.
Bou further extended the visitors' lead seven minutes after the break with another stunning goal, bringing down Sebastian Saja's goal-kick at the top corner of the box and, with his second touch, thumping the ball inside the far post.
Milito scored the fourth goal soon after, beating Liebeskind in a one-on-one, while Bou - in his first Copa Libertadores appearance for Racing - wrapped up the Argentinian club's win in the 69th minute. The 25-year-old striker tapped in Milito's cross.
Tachira's Jorge Rojas missed a penalty four minutes from time.
The victory took Racing to the top of Group Eight with Guarani set to host Sporting Cristal on Wednesday.
