Chelsea alerted as Real Madrid's Ronaldo changes agents

Real Madrid star Ronaldo has broken off the relationship with his agents, Silva Martins and Reinaldo Pitta.

Brazilian press reports state Ronaldo has joined Portuguese agent Luis Vicente, on recommendation from his Real teammate Luis Figo.

The striker's old agents are involved in a controversial court case over alleged corruption and could face eleven years in prison.

Ronaldo's contract with the pair expired in December and local press say it will not be renewed.
