Brazil midfielder Kaká insists he is far from certain of his place in the Seleção, despite impressing on his return against Iraq and Japan.
Kaká, 30, spent two years away from the national team set-up before returning with two goals in two games last month, but believes he has much yet to achieve.
“I felt good in the last two games, but nothing is certain yet,” Kaká told Lancenet. “They were two important games. I was active, but there is still much to do with the Selecão.”
While the Real Madrid man accepts that Brazil would prefer competitive fixtures ahead of the 2014 World Cup, he does not believe it can be used as an excuse.
He added: “Players feel the lack of competition. Qualification give a fear of missing the World Cup, but I don’t think this is a factor in whether you will win the World Cup or not – France in 1998 for example.
“Colombia are doing well, with players standing out for their clubs. They will be an important test for us.”
