Derry man, James McClean, looks set to captain the Republic of Ireland in a friendly against Mexico this week.
An appearance by McClean against Mexico in New Jersey would be his 50th international cap for the Republic of Ireland.
"If he [James McClean] starts the game I'm sure he will be captain," said Republic of Ireland boss, Martin O'Neill.
"We could possibly play three centre-halves and two wing-backs, James has done that before.
"It gives us the chance for a bit of experimentation," he added.
