It's November 25, 2020. A young German winger stands on the touchline anxiously waiting to step on to the Allianz Arena pitch for his Champions League debut in his hometown.

But as he waits to be allowed on, there are people watching both on television and in the largely empty stands who know this isn't how it should've been.

Rather than wearing the all-red of Bayern Munich, Karim Adeyemi jogs on in the all-black of Salzburg with the Austrian champions 3-0 down.

A technically gifted and rapid forward, Adeyemi has long been considered one of Germany's most promising young players, having cost Salzburg a reported €3million when he was 16.

Adeyemi had left Bayern six years earlier. It's a detail that has dominated much of his early professional career, with questions about why he left never far away.

Now 20, Adeyemi has previously spoken at length about his attitude as a kid, how learning wasn't much to his liking and distraction was a regular nuisance to him. These factors certainly didn't help at Bayern.

Neither, Adeyemi alleged in the past, did the club, who he said showed little support to players who strayed from "the plan". The collective, rather than individualistic talents, was prioritised.

He and Bayern were simply not a good match at the time. He left Die Roten and, while such a disappointment might've been enough to derail other ordinary kids, Adeyemi has since proven he is rather extraordinary.

A move to a smaller local club, Unterhaching, soon followed. It was there that, according to youth coach Marc Unterberger, Adeyemi was able to develop with a greater degree of individual emphasis and that eventually translated into him becoming a better asset for the team as a whole.

"He had his own thoughts on how to deal with things," Unterberger told Stats Perform in 2021. "We never wanted to change him completely, and I think we succeeded quite well. Karim is a really great guy and a great person.

"Until the time Karim came to us, we had never had such an exceptional player in our youth division.

"Of course, as a young person, you benefit from being accepted for who you are, but I would like to make it very clear that there was no situation within the team in which Karim behaved in such a way that we as a club were forced to act.

"On the contrary, over time he developed more and more towards putting himself at the service of the team. He was easily distracted, that's right, but let's be honest, something like this is normal when young people develop."

Unterberger arguably knows Adeyemi better than any other coach, given he was there for the youngster's entire six-year stay at Unterhaching.

"I can still remember it very well, the first time I saw him play in an Under-11 tournament," he recalled.

"Back then he was still playing for TSV Forstenried. My first thought was: 'We absolutely need this player'. Fortunately, it worked out later!"

That might be something of an understatement in reality. The €3m fee that Unterhaching received made him the most expensive Under-18 German player ever at the time, while 2019 saw him win the Fritz-Walter Gold Medal, an award handed out to Germany's best youth player. Previous winners include Timo Werner, Emre Can and Mario Gotze.

But most importantly, that move proved an unequivocal success for the player, as did his next.

Adeyemi confirmed to Stats Perform last year that he rejected the chance to join Chelsea from Unterhaching in his teens, instead opting to move just over the border to Salzburg. Had he gone to London, maybe he would've broken into their first-team – but it's probably just as likely that he'd have been lost among the Blues' army of loan players.

That's not to say loans can't work. Adeyemi's Salzburg career was carefully mapped out for him even before he joined, and that included an initial 18-month stint with Liefering, who essentially act as a B team. A haul of 15 goals and eight assists in the second tier provided strong evidence the teenager was ready for the step up in 2020.

His introduction to top-tier football wasn't quite so explosive, only having a hand in goals in six of his first 29 Austrian Bundesliga matches, but a key factor here was the need to remain patient – only nine of those 29 games were as a starter.

It wasn't until the final three months of 2020-21 that Adeyemi began to nail down a starting role, with seven of his 11 starts coming between mid-February and the end of May. This period also yielded six of his seven league goals.

This proved the final push he needed – with Patson Daka leaving for Leicester City, Adeyemi went from being the forwards' supporting act to the leading man in attack.

As you'd expect, this led to a bit of a change in his role, but there's no doubt he's thriving, securing his first senior international cap in September and finding himself linked heavily with Borussia Dortmund.

Sure, chance creation frequency is down (2.7 per 90, to 1.6), but the pay-off in terms of his effectiveness in front of goal is more than worth it.

His 14 goals is a league high, while only Kelvin Yeboah (11.2) – who has since joined Genoa – can better Adeyemi's 10.1 non-penalty expected goals (np-xG). Though on a per-90-minute basis, Adeyemi ranks first in the division with 0.72 np-xG (minimum 650 minutes played).

But it would be doing Adeyemi a huge disservice to give the impression he's 'just' some poacher. He's an immensely exciting player characterised by his explosive pace, low centre of gravity and silky ability on the ball. Yeboah (21) is the sole forward with more carries leading to shots and chances created than Adeyemi (21), though the Ghanaian's total comes from nearly 300 minutes more on the pitch.

It's a similar story in the Champions League. His carries led to a combined total of eight shots and chances created in the group stage – the only Opta-defined strikers to better that were Kylian Mbappe, Cristiano Ronaldo (both nine) and Arnaut Danjuma (14).

Even if it's reductive to just look at that metric, there's no doubt his performances have translated to European football's biggest stage – Sevilla's Diego Carlos will have been hoping to never see the youngster again after terrorising the Brazilian in the group.

Adeyemi's displays were a major factor in Salzburg reaching the knockouts of the Champions League for the first time in their history.

It would be a truly inspirational tale were it to be him, the young Bavarian cast-off, who plotted Bayern's downfall this time.

Karim Adeyemi will not be leaving Salzburg in January despite an explosive start to the season, according the Austrian club's sporting director Christoph Freund.

The 19-year-old forward has long been touted as a potential star of the future, having originally been in the Bayern Munich academy as a child before being let go and joining Unterhaching.

It was there that he attracted the interest of numerous foreign clubs and he ultimately picked Salzburg, with Chelsea among those he turned down, and the move has so far gone well.

After an impressive 18 months on loan at Salzburg's sister club Liefering in the second tier, Adeyemi got his chance at the Red Bull Arena early last year as he played 10 Austrian Bundesliga games before the end of the season.

Then in 2020-21, his playing time increased again with 29 appearances, and he has really kicked on this term, the teenager's 11 league starts the same he was given last season as he has become a central figure.

Adeyemi's 10 league goals is three more than anyone else in the Austrian Bundesliga this term, while he has also got three in the Champions League – only four players (including Robert Lewandowski and Mohamed Salah) have more.

A lively and technically gifted striker who likes to run at defenders, with his 60 dribble attempts the most of anyone in Austria's top flight this season, it is understandable that many clubs are reportedly keen on bringing him in.

Borussia Dortmund and Liverpool are among those to have been mentioned, but Freund doubts any transfer will occur before the end of the season.

"Karim will finish the season with us," Freund told Sky Austria. "He should fill the role he has right now for the whole season.

"That is clearly the main focus in Karim's head, and also in ours. I don't know what would have to happen, what scenario would have to occur, for Karim to not finish the season with us.

"He is on the right track and enjoys playing. That fits in well here."

Adeyemi's form this season has seen him break into Germany's senior national team as well, with the talented forwarded playing three World Cup qualifiers and scoring his first goal in September's 6-0 win over Armenia.

It is reported that Salzburg would demand at least €30million for Adeyemi, who is contracted to the club until June 2024.

It's November 25, 2020. A young German winger stands on the touchline anxiously waiting to step on to the Allianz Arena pitch for his Champions League debut in his hometown.

But as he waits to be allowed on, there are people watching both on television and in the largely empty stands who know this isn't how it should've been.

Rather than wearing the all-red of Bayern Munich, Karim Adeyemi jogs on in the all-black of Salzburg with the Austrian champions 3-0 down.

A technically gifted and supremely fast winger, Adeyemi has long been considered one of Germany's most promising young players, having cost Salzburg a reported €3million when he was 16.

Adeyemi had left Bayern six years earlier and is a situation that has dominated much of his early professional career, with questions about why he left never far away.

Now 19, Adeyemi has previously spoken at length about his attitude as a kid, how learning wasn't much to his liking and distraction was a regular nuisance to him.

These factors certainly didn't help at Bayern. Neither, Adeyemi alleged in the past, did the club showing little support to players who strayed from "the plan". The collective, rather than individualistic talents, was prioritised.

But to speak to him in 2021, Adeyemi comes across as grounded and professional, yet driven, well aware of the level he wants to reach.

"I think it's a dream for every player to play in the Bundesliga or Premier League one day," he tells Stats Perform News. Yet, should he end up in England, it's fair to say he'll have taken the long route.

Chelsea were a keen admirer of Adeyemi before he joined Salzburg, the youngster confirming in the past that he turned down a move to Stamford Bridge in favour of Austria.

"I decided that with my family because I thought that Salzburg was the best destination for me," he continued. "Their playing style fits me well and we harmonised perfectly. I got along well with Christoph Freund [Salzburg sporting director] and everyone else. That's why I decided to join this club."

But while the average football fan might question his choice, Adeyemi's former coach at Unterhaching – with whom he spent the six years between Bayern and Salzburg – believes it was a mature decision that made perfect sense.

"Surprised? No, not at all. For him, Salzburg was the right club," Marc Unterberger told Stats Perform News. "Their philosophy suits him perfectly, and the proximity to Unterhaching, where his family still lives, is ideal.

"What is being done there, especially in training young players, is absolutely remarkable."

But what exactly has that meant for Adeyemi? The teenager adds: "It was my plan to first join Liefering [on loan] when I arrived at Salzburg. I wanted to perform well there and show my skills, then I wanted to have more and more contact with the first team [at Salzburg], and I think for every young player it's first of all important to get settled. Now I am at the first team and I am happy about it. That was my plan so far."

After spending a year and a half at Liefering, who essentially act as a B team for Salzburg, Adeyemi returned to his parent club having caught the eye in Austria's second tier.

He scored 15 goals and got eight assists in 35 league games for Liefering, strong evidence that he was ready for the step up.

Adeyemi hasn't been quite so explosive with Salzburg, only having a hand in goals in six of his 29 Austrian Bundesliga matches, but the key factor here is that he is having to remain patient – only nine of those 29 games were as a starter.

"Well, you can never be completely satisfied," he explained. "You always have things to improve. It was the same for me when I played in Liefering. I always want more. It's exactly the same here in the first team. I always say I am never satisfied with what I do, I always want more, and I think that's what I am focusing on.

"I am trying to improve my game together with the coaching staff. I'm trying to have progress in my development. Nobody knows what happens in the future."

It is a display of maturity and realism that belies many of the stories that have followed Adeyemi during his fledgling career. Unterberger believes the youngster is often shown in a negative light, adamant most kids are prone to distraction.

"I find that he is portrayed too negatively. Of course, Karim wasn't a classic academy player. He had his own thoughts on how to deal with things. We never wanted to change him completely, and I think we succeeded quite well. Karim is a really great guy and a great person.

"Until the time Karim came to us, we had never had such an exceptional player in our youth division. Of course, as a young person, you benefit from being accepted for who you are, but I would like to make it very clear that there was no situation within the team in which Karim behaved in such a way that we as a club were forced to act. On the contrary, over time he developed more and more towards putting himself at the service of the team.

"He was easily distracted, that's right, but let's be honest, something like this is normal when young people develop."

After all, Unterberger arguably knows Adeyemi better than any other coach.

"I can still remember it very well, the first time I saw him play in an Under-11 tournament," he recalls. "Back then he was still playing for TSV Forstenried. My first thought was: 'We absolutely need this player'. Fortunately, it worked out later!"

That might be something of an understatement in reality. The €3m fee that Unterhaching received made him the most expensive German under-18 player ever, while 2019 saw him win the Fritz-Walter Gold Medal, an award handed out to Germany's best youth player. Previous winners include Timo Werner, Emre Can and Mario Gotze.

And he has certainly shown flashes of his significant potential. In November, he became the first player this season to have a hand in four goals (one scored, three set up) in a single game in the Austrian Bundesliga. Only one other has matched that feat this term: his team-mate, Mergim Berisha. In December, he broke Salzburg's record for their youngest ever scorer in the Champions League.

Yet Adeyemi recognises he still has a long way to go.

"I can only talk for myself and not for the other players. I think if you feel comfortable within a team and you get your chances, then there's a possibility [of finding the right fit]. That's how it is between Salzburg and myself. I will continue to work hard for that. I want to develop more and become a man."

Given the talents Salzburg and their Red Bull sister club RB Leipzig have produced in recent years, few would doubt Adeyemi's in the right place to spread his wings.
