Wales boss Chris Coleman has held 'positive' talks with Aaron Ramsey about the possibility of calling up Ryan Shawcross, but admits it is still a sensitive topic.
Shawcross was born in Chester and has previously been named in England squads, but he has yet to make his senior international debut and is eligible to play for Wales after being raised in the country.
Coleman has previously admitted that he would be interested in contacting Shawcross, but recognised that he must first consult Ramsey.
The two players have history after Ramsey suffered a sickening leg injury following a challenge by Shawcross in a Premier League match between Stoke and Arsenal in February 2010.
Coleman said: "I had a conversation with Aaron when I was in Cardiff and it was very positive, but there is an issue there.
"The point is to play football and be successful, you don't have to be best mates.
"I don't have to talk to you as long as it works on the pitch; you don't have to be best friends.
"The best dressing rooms I have been in have been edgy.
"That's what I tried to tell Aaron, he is a professional at the end of the day and he wants what is best for Wales. He wants to be captain of a winning Welsh side.
"I can make it as nice for the players as I can, they can come away and have a good time, but if they are not winning what's the point?
"What's the strongest team we can get on the pitch? That's what it is about."
Shawcross has previously made it clear that he wants to pursue an international career with England but he has fallen down the pecking order over the past couple of years and Coleman also plans to hold talks with Stoke boss Tony Pulis.
"We haven't decided anything, I still haven't spoken to Ryan or Tony yet but I will do," he said.
"If it's going to make us better then I will do it.
"I've got to be respectful of Tony. We've got Bosnia this week so it won't be before then, but I will after that."
Coleman also confirmed his intention to include Cardiff defender Ben Turner in his squad in the future.
Turner, who qualifies for Wales through his grandmother, is not in the squad for Wednesday's friendly against Bosnia-Herzegovina, but Coleman is an admirer of the player having worked with him at Coventry.
But Coleman says it will be a while before he can include Shawcross, even if the England Under 21 international does decide to play for Wales.
He said: "The way it works with Ryan is that because he has been with England Under 21s that if, and it is if, he decided he wanted to come with us and we wanted to take him it's not cut and dried.
"It's a long process that can take two months and it's about the committee that decides these things coming together, not just the Welsh FA.
"Ben Turner qualifies and I like Ben. I have not had a conversation with him yet, I left him to enjoy his summer but I like Ben.
"I had him at Coventry and he's come on leaps and bounds."
