The Stoke captain has just one England cap to his name, which he earned in November's 4-2 friendly defeat in Sweden, but his manager insists he can earn many more.
"First and foremost, and he will tell you the same, his priority is to be a success here and do well," said Hughes.
"But I have had conversations with him and the England situation is one he feels he can be a part of again.
"If he has a good season with us, and it is World Cup year, who knows? He is certainly capable of playing international level.
"He is enjoying having more responsibility in possession. And having more possession gives you a rest so that when he has to defend he can be more dynamic."
