Brazil coach Luiz Felipe Scolari, taking charge of his second match since being re-appointed in November, said on Wednesday that Kaka will be under the microscope as he continues to look for his ideal team for the Confederations Cup in June and next year's World Cup.
Scolari tested 32-year-old Ronaldinho in last month's friendly against England but the former Barcelona and AC Milan player failed to impress, as he missed a penalty and was substituted at half-time after a ponderous display.
The coach, known as 'Big Phil', had already made it clear he would test former World Players of the Year Kaka and Ronaldinho separately before deciding whether they were suitable for 2014.
"The idea is to bring him [Kaka] on during the [Italy] game and maybe let him start in the match against Russia," Scolari told reporters.
"We want him to show his potential and whether he is in the right condition or not. We want to observe how he blends in with the other players, compare his characteristics with the other players."
"Then we will analyse if they can play together, if they can not play together, or if one will be chosen, or neither," he said.
"I have had one training session, one game and one more training session," he said. "I have to make the most of these to test things which I think could work during the games.
"The matches are our training sessions."
