Iheancho, who was named the Most Valuable Player at the 2013 Fifa U17 World Cup, began the exploit after four minutes with a close range finish.
He added his second from the penalty spot after Raheem Sterling was brought down by Leandro Bacuna before sliding home his third on the counter in the second half.
And the world football governing body through their Twitter handle acknowledged the Super Eagles’ star performance against Remi Garde’s men.
“U-17 World Cup star in 2013 Hat-trick hero in the FA Cup today congrats, Kelechi Iheanacho,” Fifa tweeted.
