Brazil [ Images ] have added Real Madrid [ Images ] striker Julio Baptista [ Images ] to their Copa America squad after midfielder Ze Roberto quit international football.

Baptista, who was unable to secure a regular first-team place in his season on loan at Arsenal [ Images ], has not played for his country since the 2-0 win over Wales in a friendly last September.

Former Bayern Munich [ Images ] midfielder Ze Roberto pulled out of the squad last Friday, two days after being recalled for the first time since the 2006 World Cup.

"After much personal meditation, I reached the conclusion that, at the age of 32, I cannot serve the Brazilian national team with the quality required in the current circumstances," he wrote in a letter to the Brazilian Football Confederation (CBF).

"Similarly, I will not be as useful to the group as I was on previous occasions."

Ze Roberto has been in outstanding form for his club Santos, leading them to the semi-finals of the South American Libertadores Cup, where they last over two legs to fellow Brazilians Gremio.

Venezuela host this year's Copa America from June 26-July 15.
