Alfie will become one of a number of young Northern Irish players who have made the move over to Premier League clubs from Northern Ireland.
Players such as Tottenham Hotspur Academy’s George Feeney and Josh Kerr, who has just signed a professional deal at West Ham, are currently based in England.
Fellow youngsters Braiden Graham, at Everton, and Arsenal’s Ceadach O’Neill have both have been on the bench for the senior squad and both play within the Northern Ireland u19 set-up.
At senior level, Liverpool’s Conor Bradley, who played for Dungannon Swifts, and former Linfield and current Sunderland defender Trai Hume have also made the move from Northern Ireland.
Mulvenna’s progress through the JD Academy and within the Northern Ireland set-up has been clear with his dad excited to see what the future holds for his son.
“I am his biggest fan,” Haveron said.
“It’ll be hard to see him go, but we are excited because it is all he has ever wanted to do and to be given the opportunity at a Premier League club like Crystal Palace is huge for him.
“It’ll be quite a change from a small town like Larne, but he is ready for it. He has worked so hard for it and he deserves the opportunity.”
Despite being so young, Alfie added that he wouldn’t have been able to secure the move if it wasn’t for his dad.
Now, he aims to make his family proud when he heads to England to begin the latest chapter of his football career.
“All we talk about is football, but I appreciate everything he has done for me, “he continued.
“It has helped me get to where I am today. I want to make my family and friends proud when I get over.
“All I can do is work hard and try my best and, with a bit of luck, I will get to the top.”
