Former Chelsea manager Jose Mourinho is at the centre of an alleged bribe investigation.

The Daily Mail says the Portuguese Home Office are investigating claims that former Chelsea boss Jose Mourinho bribed the author of a book not to reveal details of his alleged extra-marital affair.

Mourinho is alleged to have paid an unspecified amount to Carolina Salgado, the former partner of Porto president Jorge Nuno Pinto da Costa, not to reveal the story in her autobiography.

Carolina's sister, Ana, alleges the authoress changed the book to exclude the allegations.
