Real Madrid must sign AC Milan defender Digao if they want to complete a world record deal for Kaka.

The Sun says Kaka has a list of demands Real must meet if he is to choose them ahead of Chelsea - or remaining at the San Siro.

Those are:

- His family must be set up financially for life.

- His father Bosco Leite must get an astonishing £10million commission for acting as the go-between in the transfer.

- Kaka's brother Digao, who is a centre-back at AC Milan, must be signed at the same time.

A source close to the negotiations said: "This transfer is far from straightforward.

"There are a lot of complications and for Kaka he must be satisfied that his family is taken care of."
