Coyne knows he must be playing on a more regular basis than he achieved for English third tier club Colchester United last season - if indeed he remains with the U's.

He remains under contract with the Essex club and it isn't yet clear if they are willing to consider offers for him.

But should Coyne remain with Colchester, he won't be offered any special selection treatment by boss Paul Lambert.

He told the Colchester Evening Gazette: "I don't want to stop anyone from going to play in a World Cup. To go to a World Cup is the pinnacle of any player's career.

"But he has to play and we can't guarantee that, just like we can't guarantee that to anyone.

"If he doesn't play here, I'm pretty sure the manager there (Pim Verbeek) will say, 'hang on a minute, what's going on there?'."

At least there is some encouragement for Coyne in the fact that Lambert has no complaints about the player's performances when he was selected for Colchester last season.

"He has done really, really fine for me whenever he has played and he's been playing well at the minute for them," said the U's boss.

Colchester chief executive Steve Bradshaw said the U's will try to find a solution that suits both Coyne and the club.

He said: "We don't want to lose such an experienced international but we will do what is best for him and for the club."

Coyne has been linked with A-League clubs Perth Glory (home to his brother Jamie) and also Sydney FC.
