Northern Ireland boss Nigel Worthington believes in order for his team to improve his regulars need first-team football at club level.
Almost half of Worthington's squad cannot hold down regular football with their respective club sides and the 47-year-old wants that to change.
The former Norwich and Blackpool manager believes it would be beneficial to the county if his stars went out on loan, rather than warming the first-team bench or worse.
"It certainly doesn't help us," said Worthington. "Players need to be forcing their way into their teams.
"Otherwise they will have to sit down with their managers and if needs be either move on or go out of loan."
One of the players Worthington is referring to is Sunderland's David Healy, who has managed just three Premier League appearances this season.
Northern Ireland number one Maik Taylor thinks the intense competition for places at The Stadium of Light could force to striker to move on.
"There's strong competition for places at Sunderland and the worst-case scenario is that David will maybe move on," said Taylor.
