Sport says Kaka is unimpressed by Milan's signing of his Brazilian rival. He fears the team spirit at Milan could go the same way as what happened with Brazil during the 2006 World Cup, which led to Kaka questioning the commitment of some of his Selecao teammates.

Kaka's lifestyle simply doesn't square with Ronaldinho's and he is now seriously considering jumping ship and joining Luiz Felipe Scolari, who is also deeply religious, at Chelsea.
