Wigan Athletic boss Roberto Martinez is convinced James McCarthy can be a Euros star with the Republic of Ireland.

Martinez is in no doubt that the player can rise to the occasion against the likes of Spain, Italy, Germany and England if given the chance.

"When any of our players go away with their countries for international duty, it makes them better players, better individuals," Martinez told the Wigan Evening Post. "Any experience of major tournament football brings them on even more, and I expect that to be the case with James next summer.

"To be involved with a senior squad at the age of just 21 is a phenomenal achievement, and to sample a major finals would be a unique opportunity to move on to the next level."
