A day after announcing Melbourne City's signing of Tim Cahill, Football Federation Australia is ramping up its pursuit of Ronaldinho and Diego Forlan with negotiations set to take place as early as next week.

The brother and agent of Brazilian star Ronaldinho will land in Sydney on Monday for scheduled talks with the FFA over a possible move to the A-League.

While discussions are yet to include A-League clubs, the 10 members have been put on notice about the availability of the 36-year-old as a guest player. Under the new regulations, a guest player paid outside of the salary cap can be registered for the entire season, however those adjustments may still not be sufficient enough to sway some potential suitors in the A-League.

As part of the marquee fund allocated to star signings, the FFA is taking a more active role in negotiations for major recruits and is understood to be involved in talks for Uruguayan striker Forlan to Brisbane Roar.
