Football Federation Australia chief executive David Gallop says A-League clubs may still find it difficult to sign high-profile international stars even with the new guest-player slot.FFA recently introduced a full-season guest player role tailor-made to help Melbourne City sign Socceroos veteran Tim Cahill.However Gallop warned clubs will still be hard-pressed to lure big, marketable names to Australia as they struggle to balance star power with a desire to win games - all in a salary-cap system.Its always tough, Gallop said on Monday after announcing Hyundais four-year A-League sponsorship extension.Theres a big expectation about big-name stars, but football coaches want to win games so theres always a balance of how they approach that.Weve loosened the rules, if you like, around the full-season guest capacity of clubs in that space.But we dont necessarily think its easy to get big-name players.There are leagues overseas offering a lot of money and we have to be conscious that we operate in largely a salary-cap environment, an environment where private investors are putting their hand in their own pocket.The guest player spot - essentially a third marquee player who meets FFAs key commercial metrics - has increased conjecture Cahill is set to join City as the new face of the A-League.Gallop met with Cahills management the week before last but on Monday said there were no fresh developments, only reiterating Australias all-time leading goalscorer would provide a valuable boost.His comments came as the leagues first and only naming-rights sponsor Hyundai re-committed until the end of the 2019-20 season.The partnership will also extend to a 15th season, expanding to include rights to the Socceroos, Matildas and W-League.The new four-year deal, which Gallop said was worth millions of dollars and represented a significant uplift on the last, does not include incentives for expansion.But he said that did not necessarily rule out more teams before 2019-20.Gallop expected some clubs to take advantage of a change in regulations allowing them to sign with rival car manufacturers in deals upwards of about $500,000.City started the trend by joining forces with Nissan this month.Obviously not everyone will go into that space, he said.But I think we will see the bigger clubs with that kind of sponsorship in upcoming seasons.
