MARK Bosnich doesn’t see a problem with Tim Cahill leaving Melbourne City to secure more game time, but the lack of an domestic transfer system is a roadblock for move within the A-League.

Cahill wants more minutes ahead of the 2018 World Cup and the 37-year-old was reportedly set for showdown talks with City coach Warren Joyce to discuss his role at the club.

The striker made it clear he’s open to leaving the City if more playing opportunities don’t materialise, but a move within Australia would prove difficult.

With no domestic transfer or loan system, the only way players can move between A-League teams is through a loophole where clubs simultaneously release players off their rosters so they can trade places - for example Andrew Redmayne and Vedran Janjetovic swapping Sydney teams last season.

Former Socceroo Bosnich has been calling for a domestic transfer system and believes the lack of one is the biggest roadblock to Cahill finding a new club in Australia.

But that doesn’t mean City will stop the striker leaving.

“They have to sit down face-to-face and talk it through,” Bosnich told Fox Sports’ Shootout.

“If it comes to the fact that there can be no agreement... We’re talking about the biggest club owners in the world. They won’t have a problem finding a replacement.

“Timmy’s going to be focusing on playing at the World Cup. He wants to be one of the very few players to be playing in four World Cups.

“If it’s a problem for him, Tim, from his side, I don’t see a problem with for him to go. I don’t really see Melbourne City standing in his way.

“This underlines my point why we should have domestic transfer system or at least loan system.”

He added: “They’re [City] doing fine in my opinion... but you don’t want something like this completely taking away from what’s on the park.”

Joyce has refused to comment on speculation that Cahill’s unhappy with his role at City, but former Socceroos John Kosmina and Ned Zelic don’t have a problem with the coach not picking the striker.

“I agreed with Warren Joyce to a certain extent,” said Zelic.

“His comments, the fact that it’s been difficult for him as well, the fact that Timmy has been away as well and for him to put a team out that he obviously believes in and can do the job for the team.

“That’s his job - to pretty much get to the core of this team’s strengths.”

He added: “They’ve got incredible depth and he’s got a tough job on his hands to put the best team.”

Kosmina said: “You can’t have picked Timmy in any of these games.”

“He was in and out of the camp away with the Socceroos.”

He added: “I think Warren Joyce has been putting his stamp on the squad.”
