Kirby was a member of England's victorious U17 World Cup-winning squad in 2017, and the midfielder played in six of their seven games in India, scoring the crucial penalty in a shootout win against Japan in the last-16.
Kirby signed a professional deal with the Eagles in February 2017, having previously on the books of Tottenham Hotspur before linking up with Palace at the start of 2016/17, and quickly earned himself a professional deal after impressing for the development side.
He was named on the first-team bench against his former club Spurs in February 2018, but despite featuring for Roy Hodgson's team in friendly action during the summer of 2018, he is still awaiting his full Eagles debut.
In January 2019 he joined League One side Blackpool on loan for the rest of the season.
