Scott Hogan has been named in a 32-man provisional squad for Ireland's crucial World Cup qualifiers against Moldova and Wales next month.
The Aston Villa striker received his Irish passport a few days ago and O'Neill is delighted to welcome him to the Boys in Green.
Aiden O'Brien of Millwall is another new man in the group as the Irish boss ramps up his attacking options without Jon Walters.
The Burnley man is out for "more than a few weeks" according to O'Neill and so Hogan and O'Brien have their chance.
Sean Maguire of Preston is also named the group, but the question is whether he can now make the party of 24 or 25 that will actually enter the training camp early next week.
Maguire was among those to miss out in that cut last time, and the ex-Cork City hit-man will be hoping that not even the return of David McGoldrick of Ipswich will get in his way this time.
Everton's James McCarthy is in the 32, but O'Neill admits he needs to get back playing this weekend to be involved in these vital games for Ireland.
