Barcelona teenager Lamine Yamal became the youngest player in Spain's history with his substitute appearance against Georgia in Euro 2024 qualifying.
At the age of just 16 years and 57 days old, he smashed the record his current Barca team-mate Gavi set in 2021 aged 17 years and 62 days.
BBC Sport looks at some other male players aged 16 and under who have played senior international football.
Wales - Harry Wilson
That broke Gareth Bale's Wales record by 108 days.
There had been talk that England could have tried to call up Wilson, eligible through a grandfather, until his 87th-minute appearance off the bench.
His grandfather Peter Edwards won £125,000 after betting £50 on Wilson playing for Wales, at odds of 2,500-1 when he was a toddler.
Wilson would have to wait five years for his second cap.
Ireland - Sam Johnston
Sam Johnston, aged 15 years and 153 days, played in Ireland's first ever international fixture, a 13-0 defeat by England in 1882.
That record has never been beaten - and the then Distillery forward, who died in 1910, is thought to still be the youngest European international.
That team was run by the Irish Football Association, long before Irish independence, and continued to be called Ireland until 1954 when it renamed to Northern Ireland.
Belfast's Johnston would win five caps between 1882 and 1886, scoring twice. Sadly his team lost all five games by an aggregate score of 41-5.
Stromsgodset midfielder Martin Odegaard - now the Arsenal captain - made his Norway debut at the age of 15 years and 253 days, playing all 90 minutes in an August 2014 friendly with the United Arab Emirates.
He had played 14 games for his club at that stage.
Later that year he became the youngest player, at 15 years and 300 days, to appear in a European Championship qualifier in his side's victory over Bulgaria in Oslo.
Now 24, he has won 51 caps and counting.
Brazil - Pele
He would rise to global stardom a year later, but on July 7, 1957 the precocious Santos forward Pele made his Brazil debut at the age of 16 years and nine months.
In a sign of the great things that were to come, he scored that day against Argentina at the Maracana.
He added two more World Cup triumphs with the Selecao, but it was perhaps the feats of the teenage Pele that were the most jaw-dropping of his magnificent career.
Cameroon - Samuel Eto'o
The striker, who made his name at Barcelona, would go on to be his country's all-time top scorer, with 56 goals in 118 caps, and is now president of the Cameroonian Football Federation.
Argentina - Diego Maradona
Diego Maradona of Argentinos Juniors was 16 years and 120 days old when he made his Argentina debut in a 1977 friendly against Hungary.
His first international goal was two years later against Scotland.
He would go on to become a football legend and captain the country to victory at the 1986 World Cup.
Maradona, who scored 34 goals in 91 caps, managed the national team from 2008 to 2010 and died in 2020.
Northern Mariana Islands - Lucas Knecht
The youngest men's international footballer is supposedly Lucas Knecht, who was 14 years and two days old when he played in Northern Mariana Islands' 9-0 East Asian Football Championship preliminary round loss to Guam on 1 April 2007.
However the Northern Mariana Islands, a self-governing commonwealth of the United States, is not a member of Fifa.
According to statisticians RSSSF, three 14-year-olds have played for the national team - with Joel Fruit and Kennedy Izuka both making their debuts in a November 2012 game, also against Guam. They only lost this one 8-0.
