Harry Wilson has agreed his first professional contract with Liverpool.
The 17-year-old Wales international announced his deal on Twitter.
"Delighted to have signed my first professional contract with Liverpool Football Club," he said.
Wilson, a winger, became Wales' youngest international when he made his debut aged 16 years and 207 days against Belgium on 15 October 2013 - beating Gareth Bale's previous record by 108 days.
Liverpool manager Brendan Rodgers was taken aback when Wilson was capped by Wales.
"I was surprised. Obviously Wales had a lot of injuries," he said at the time.
"To have him here at the club is brilliant," Rodgers added. "He knows he will have a great opportunity here if he continues to develop at Liverpool.
"It's important that we just stay calm and let him develop at his own rate."
Wilson earning a Wales cap also saw his grandfather win £125,000 from a £50 bet placed in when the teenager was 18 months old.
Bangor-born midfielder Jordan Williams has has also signed a professional contract with Liverpool.
