Chelsea midfielder Willian has told his lawyers to take action over a forged letter that circulated on the "football market" claiming he had given authority to another agent to represent him.
In a post on Instagram, the Brazi international published a picture of the letter, in which a man claiming to be a FIFA-registered agent called Denirobson Dias grants permission to another man by the name of Renee Pinheiro Anunciacao to act on behalf of the winger.
Neither "agent" has any relationship with Willian, and in a message alongside the picture the Chelsea star pledged to take legal action over the letter, which he says contains a forgery of his signature.
