The former Ballon D'or winner is optimistic that his side can benefit the hiatus at club-level to go on to win South America's biggest club football competition this summer
Cuca's men travel to Rosario, Argentina on Wednesday to face Newell's Old Boys for the first leg of their semi-final clash in the continent's most prestigious club competition.
However, Atletico, who are vying for their first ever Copa Libertadores title, have not played a competitive fixture since June 12 due to the country's hosting of the Confederations Cup, but the former Barcelona attacker says the interval has provided the team with an added hunger to reach the final.
Ronaldinho told the club's official channel: "We've been missing the ball.
"The break has come at a good time. We will all come back keener to play and reach the final, but the game on Wednesday will be like another final. It will be the hardest game we have played."
The second leg is scheduled to be played on July 11, with either Olimpia of Paraguay or Colombian outfit Independiente Sante Fe awaiting the winners of the tie in the final of the competition.
Ronaldinho was omitted from Brazil coach Luis Felipe Scolari's Confederations Cup squad, but both Selecao internationals Jo - who, with six goals is leading the hunt for the tournament's golden boot - and Bernard has been welcomed back by coach Cucu for the trip to Argentina.
