Here are five points to note about the midfielder:
1. Billing is at home in blue and white stripes
Born on June 11, 1996, he came through the youth system at Danish top-flight club Esbjerg fB, who wear the same colours as Town.
It’s a port city in West Jutland, in the South-West of Denmark.
Five times Danish champions and three times the country’s cup winners, most recently in 2013, EfB are currently second-bottom of the Superliga.
The club also run an elite ice hockey team.
2. It took him just 10 days to impress Town
Billing was signed after a successful trial early in 2013.
His international clearance came through on the eve of the 2013-14 campaign.
He soon became a regular at Under 18 level, and made his Under 21 debut within a month.
His first-team bow came under Mark Robins as a substitute at home to Leicester City in the final home game of that campaign.
But Billing had to wait until September’s visit to Charlton for his second appearance.
His first start came in Chris Powell’s last match as manager, the 2-2 draw at Reading in November.
He has now made four starts and seven first-team appearances in all.
3. Billing is contracted until 2017
And the good news is Town have the option of adding another 12 months.
His current deal was penned in October 2013.
At the time academy manager Mark Lillis said: “He is showing great promise and has successfully made the transition from his home in Denmark to life in England and deserves credit for that.”
4. He has grown while in West Yorkshire
Sky Bet Championship - Reading (2) v Huddersfied Town (2) - Philip Billing.
Logged at 6ft 4in when he joined, Billing now stretches the tape to around 6ft 6in according to Town’s website.
The 19-year-old weighs in at 13st.
He is naturally left footed and has performed a variety of midfield roles while at Town.
5. He has played once for his country
Billing went on as a substitute for Denmark Under 19s in a 2-1 win over Norway in September 2014.
The game formed part of an international tournament also involving Sweden in Lyndgal, Norway.
