RIO DE JANEIRO, April 9 (Xinhua) -- Defending Copa Libertadores champions Atletico Nacional will be hoping to break a sequence of six international matches without a victory when they host Brazil's Botafogo in South America's top club competition on Thursday.

The Colombian side have struggled to fill the void left by the recent departures of Davinson Sanchez, Sebastian Perez, Alejandro Guerra, Marlos Moreno, Miguel Borja, Jonathan Copete and Orlando Berrio.

"We are still trying to assemble our team," Nacional coach Reinaldo Rueda said. "It's a process that is working in some of our matches but we are still waiting to get results in the Copa Libertadores."

Nacional are currently third in Group A, having lost their only match so far to Barcelona de Guayaquil.

In the past six months, the Medellin outfit have lost three and drawn three of their six international fixtures across three competitions: the Copa Sudamericana, FIFA Club World Cup and Recopa Sudamericana.

Also aiming to end a winless run are Rio de Janeiro giants Flamengo, who will host fellow Brazilian side Atletico Paranaense at the Maracana stadium on Wednesday.

Flamengo have failed to win in their past four matches in all competitions and were eliminated from the Rio de Janeiro Cup on Saturday after a 0-0 draw with Vasco da Gama.

"It's uncomfortable, any sequence of matches without winning is undesirable for a club like ours," coach Ze Ricardo told reporters.
