Killian Phillips has completed his move to Crystal Palace from Drogheda United.
The midfielder, who can also play in defence, has signed a two-year contract and will initially join the Under-23s.
Drogheda have received an undisclosed fee for the highly regarded 19-year-old who made 31 appearances last season.
"He's an exceptional talent and is proof that Drogheda United is a club that nurtures and develops young players to meet their potential," said Drogs boss Kevin Doherty.
And in a Drogheda statement confirming his departure from the League of Ireland, the Co Louth club said he has the potential to play for Ireland in the future.
Phillips impressed the Premier League outfit during a trial before Christmas and returned to London to train with the Under-23s before the festive period.
Phillips will be managed by Paddy McCarthy, the former Ireland Under-21 and ‘B’ international who made over 130 appearances for the club as a player.
“I’m delighted to be here and I’m proud to be a Crystal Palace player,” said Philips.
“Paddy was talking to me about signing for different clubs.
“He said to me it’s like buying a home: when you walk into the right home you know it’s the right place, and that’s kind of how I felt at Crystal Palace the first day I walked in.”
And Palace U23s boss McCarthy said: “We’re delighted to get Killian on board.
“He had a great season last year in the League of Ireland with Drogheda United and he fits the profile of young, hungry players we want at our club.
“We believe Killian has great potential to develop and all the attributes to have a career in the game.
“He will definitely add to the group both on and off the pitch with his experience of first-team football.
“I’m sure he will benefit from working with a fantastic group of young, hungry players in a top-class environment.”
