The A-League's quality will suffer when the number of foreign imports are reduced, warns Adelaide United coach Josep Gombau.
A-League clubs are set to have the number of foreign visa players reduced from five to four from the 2015-16 season, a move Gombau says could back-fire.
"For me, now the league is nice, the league has big value," the Spanish coach said on Thursday.
"The moment that you start to cut the numbers of the foreign players that come, maybe the level of the league decrease a little bit."
Gombau was puzzled by Football Federation Australia's rationale for the change.
"The federation make this because they want the players from Australia to play a little bit more," he said.
"But in the end, how many players from Australia that are playing in the A-League are going to the Socceroos?
"A lot of (Socceroos) players are overseas.
"We need to find the balance ... and it's important that the players in Australia want to stay in their league.
"If these players want to stay in the A-League, the A-League needs to be competitive and for the A-League to be competitive they need good players - sometimes the players that make the difference are the foreign players."
