Ronaldinho says Atletico Mineiro has "no greater wish" than to win the Copa Libertadores for the first time in the club's history.

The Brazilian club will face Paraguay's Olimpia in the final of South America's most coveted club trophy following their dramatic penalty shootout victory over Newell's Old Boys in the semifinal.

The decider's first leg will be played in Asuncion on Wednesday and the return match in Belo Horizonte on July 24.

"We are training hard for these last two matches," Ronaldinho wrote on Twitter. "We have no greater wish than to bring the title to Atletico."

Ronaldinho's team travelled to Asuncion on Monday evening and will train just once in the Paraguayan capital before Wednesday's duel.

The former Barcelona star has been one of the form players of the competition with four goals and eight assists from 12 matches.
