Brazil coach Luiz Felipe Scolari will likely choose between Ronaldinho and Kaka for his squad at the Confederations Cup in June.

The coach says in an interview with Folha de S. Paulo newspaper published Monday that he almost certainly won't pick both players when Brazil hosts the World Cup warm-up tournament.

Scolari says he gave enough chances to both players, adding there's a "90 percent chance" that he will select only one of them for the squad.

The coach says Brazil is "on the right track" heading into the Confederations Cup, and that only a few adjustments need to be made before it opens against Japan on June 15.

Looking ahead to the World Cup, Scolari says Germany, Italy, Spain and Argentina are set to be Brazil's top challengers.
