Florentino Perez could wreck Manchester City's plans to land AC Milan ace Kaka this month.

Gazzetta dello Sport says Perez is planning to challenge for the Real Madrid presidency and intends to secure Kaka's commitment to his ticket.

With Real president Ramon Calderon facing calls to quit and set to declare early elections for this year, Perez could deliver Real fans what Calderon failed to do - Kaka in time for the start of next season.
