"My objective is to do my best with Flamengo and if the coach needs me I will be ready," said Ronaldinho, who returned home in January 2011 after a two and a half year spell with Serie A giants AC Milan.
Menezes, who replaced Dunga after the 2010 campaign, selected Ronaldinho for a friendly against Argentina in Doha last November but he has since been left out of squads for a string of friendlies and the Copa America last month.
But having scored a memorable hat-trick for Flamengo in a 5-4 win over league rivals Santos last month, the 31-year-old Ronaldinho is firmly back in the public domain—and wants Menezes to sit up and take notice.
"It's the moment I've been dreaming of (to return to the Brazil squad). Physically, I'm in top form," he added.
"From now until the World Cup a lot of things can happen, but I believe I can make a positive contribution to the national team."
Brazil's next game is a friendly against Germany in Stuttgart on August 10.
