sport news Wayne Rooney became a world-beater, while Theo Walcott failed to live up to the ... trends now
Kobbie Mainoo's meteoric rise continued on Tuesday when he was called up to the England senior squad for the first time by Gareth Southgate.
Having initially been left out last week, the Manchester United midfielder received his promotion from the Under-21s after starring in his side's dramatic 4-3 FA Cup win against Liverpool on Sunday.
Should he play against Brazil or Belgium in the coming days, Mainoo would become just the 14th male player this century to make his England debut before turning 19.
But how did the other 13 players before him fare?
Mail Sport has taken a look at those starlets and whether they went on to shine or if they fell short at the highest level after bursting onto the international stage.

Walcott was a shock inclusion in England's 2006 World Cup squad, having never previously played in the Premier League.
He did enough to catch Sven-Goran Eriksson's eye at Southampton, and was selected for the tournament in Germany, becoming England's youngest-ever male debutant in a warm-up friendly against Hungary.
But he did not play a single minute in Germany, and went on to never feature at a World Cup after being snubbed in 2010 and then missing out due to injury four years later.
Walcott spent 12 years at Arsenal and earned 47 international caps, but only scored eight goals for his country, with three of those coming in one game during a 4-1 win against Croatia in 2008.
After being viewed as one of the most exciting prospects England has ever produced, Walcott failed to live up to the hype in the end. He finished his career back at Southampton, retiring last year after being released by the Saints.

Rooney announced himself by scoring a stunning winner for Everton against Arsenal just days before his 17th birthday in October 2002. Four months later, England came calling.
He instantly looked at home on the international stage, despite England losing 3-1 to Australia on his debut. Just over a year later, Rooney scored four goals at Euro 2004 and was picked up by Manchester United that summer.
It quickly became apparent that he was one of the best players in the world, although his lack of goals at future tournaments led to some criticism from fans.
However, the numbers speak for themselves. Rooney is England men's second-highest goalscorer of all time with 53 - having been overtaken by Harry Kane last year - and is his country's most-capped outfield player having made 120 appearances for the Three Lions.
There have not been many better players to pull on the England jersey over the years.

Bellingham is well on the way to emulating Rooney, and may even surpass his achievements for England.
He started for his hometown club Birmingham City just days after his 16th birthday in August 2019, and was picked up by German giants Borussia Dortmund a year later.
In November 2020, the midfielder was handed his England debut in a 3-0 friendly win against Republic of Ireland.
He has only gone from strength to strength since then, and is now at Real Madrid where he has scored 20 goals in his maiden season.
Bellingham already has 27 caps and he does not turn 21 until June. He is one of the first names on the England teamsheet, and if he continues to progress at his current rate he will smash all records.

Sterling looked the real deal as soon as he moved into Liverpool's first team squad, and he made his England bow in November 2012.
The Three Lions lost 4-2 to Sweden that night in a game largely remembered for Zlatan Ibrahimovic's incredible bicycle-kick goal from 30 yards out.
Sterling was unable to take centre stage on that occasion, but he became a key player under Roy Hodgson and then Southgate.
He has not always been appreciated by England fans, with some turning on him during Euro 2016, while his finishing was also questioned at the 2018 World Cup.
But he thrived at Euro 2020, scoring three goals as England reached the final before losing to Italy on penalties. He has 82 caps and 20 goals to his name, but looks unlikely to add to those tallies any time soon, having not featured for his country since December 2022.

Hudson-Odoi emerged as a major prospect at Chelsea before he had even turned 18, and was linked with a switch to Bayern Munich.
The Blues managed to keep hold of him and he won his first England cap during a 5-0 victory against Czech Republic in March 2019.
But he struggled to kick on after that due to injuries and inconsistent form, and has only played three times for England, meaning he is still able to switch allegiances to Ghana, who he qualifies to play for through his parents.
After a year on loan at Bayer Leverkusen, Hudson-Odoi was sold to Nottingham Forest last summer.
He has not made an England squad in over four years, and is some way down the pecking order due to the national side's wealth of talent in wide areas.

Richards became England's youngest-ever defender in 2006 and is happy to remind everyone that he 'burst onto the scene' as a teenager.
He certainly was seen as a huge prospect when he broke into the Man City team, and he was rewarded with his first England cap in a 1-1 draw against the Netherlands.
Richards starred in City's 2011-12 title-winning season, and also lifted the FA Cup and Carabao Cup during his time at the club, but his international career never took off.
He was often left playing second fiddle to Glen Johnson at right back, and only won 13 caps in total.
His playing career was curtailed by a knee injury, forcing him to retire at just 31, and he now works as a pundit for multiple broadcasters.

Sancho left England as a teenager to move to Borussia Dortmund and it paid off as he began to shine straight away, leading to him gaining international recognition.
His debut was a rather forgettable affair as England drew 0-0 in Croatia in October 2018, but it was still clear England had a special talent on their hands.
Sancho continued to thrive at Dortmund and was snapped up by Manchester United for £73m in 2021 after a lengthy pursuit, and it seemed a
