The article below from Soccerly is interesting, it seems Keane would love to have Magic Mike playing in green and white with him.
"Keane...was informed by the Chicago hitman of his Irish heritage and his willingness to investigate the link. Of Magee the Irish international said, "His whole family is Irish. His grandfather or father. I’d say he would play for us. He definitely would like to but he’s probably waiting for that American call-up. He’s not an international. How he hasn’t got it I don’t know.""
"Magee has previously been capped at both U-17 and U-20 level, but neither would rule him out of representing the Irish team, as long as he qualifies through his grandparents."
