Alejandro Garnacho's football career was once heading in one direction: straight towards superstardom. The Argentine winger was being hailed as one of the brightest young talents in world football, a Manchester United academy sensation capable of producing match-winning moments that reminded fans of Cristiano Ronaldo.
Fast forward only a few years, and the picture could hardly be more different. After falling out of favour at Manchester United, struggling to establish himself at Chelsea and now finding himself on the bench at Aston Villa, Garnacho's career has taken a stunning downturn.
The latest setback came against Coventry City in the Carabao Cup. Despite Unai Emery making seven changes to his Aston Villa starting XI, Garnacho remained an unused substitute as Villa won 3-1. Emery subsequently admitted that the winger is currently behind several of his teammates in the pecking order.
For a player once tipped to become Manchester United's next superstar, that is an extraordinary fall.
Garnacho's rise: The next Cristiano Ronaldo?
When Erik ten Hag arrived at Manchester United, one of the brightest developments of his early tenure was the emergence of Garnacho.
The teenager had already impressed at the youth level, helping United win the FA Youth Cup in 2022, but his transition into the senior side was spectacular. Garnacho was fearless, direct and incredibly unpredictable. He had the pace to attack defenders, the confidence to demand the ball and, most importantly, an ability to produce decisive moments.
His breakthrough season in 2022/23 produced four goals and six assists in 10 starts, alongside 19 substitute appearances.
Then came the moments that turned him from an exciting prospect into a genuine phenomenon.
Garnacho scored a dramatic late winner against Fulham in November 2022, while his performances in the Europa League and Carabao Cup further established him as one of United's most dangerous young attackers. The comparisons with a young Ronaldo were almost unavoidable.
And it made perfect sense.
Ronaldo was Garnacho's idol. He grew up admiring the Portuguese superstar, and his explosive playing style, confidence and celebration only strengthened the similarities in the eyes of United supporters.
By 2023/24, Garnacho was becoming a regular and delivering on the biggest occasions. His spectacular overhead kick against Everton won the Premier League's Goal of the Season award and eventually the FIFA Puskás Award. He also scored twice against Aston Villa, twice against West Ham and twice against Chelsea during the campaign.
Then came the defining moment: the FA Cup final against Manchester City.
Garnacho opened the scoring at Wembley before Kobbie Mainoo added another as United defeated their neighbours 2-1. The two teenagers became the first pair of teenagers to score in an FA Cup final.
Suddenly, Manchester United supporters had every reason to believe they had discovered another special academy superstar.
And perhaps, more importantly, they believed they had finally found the player who could carry the legacy of the legendary No. 7.
The Amorim era changed everything
The problem was that Garnacho's rise happened under a system that suited him.
Ten Hag's 4-3-3 allowed him to operate naturally as a winger, where his pace and directness could be maximised. When Ruben Amorim arrived, however, the tactical environment changed dramatically.
Amorim's 3-4-2-1 system did not naturally provide Garnacho with the same role. The Argentine found himself competing for positions that did not necessarily maximise his strengths, while questions surrounding his tactical discipline and attitude increasingly became part of the story.
There were also incidents away from the pitch.
Garnacho was criticised for his behaviour, social media activity and reactions to being substituted or left out. One particularly damaging incident came after he was substituted against Ipswich, when he walked straight down the tunnel before later apologising to his teammates. His relationship with Amorim eventually deteriorated to the point where he was effectively pushed towards the exit.
Garnacho himself later admitted that he had done "bad things" during his final months at Manchester United and could have handled his departure differently.
Eventually, Chelsea came calling.
Chelsea was supposed to be the comeback
When Garnacho joined Chelsea for around £40 million in 2025, there was a widespread feeling that Manchester United might eventually regret selling him.
Chelsea offered him a fresh environment, a new manager and an opportunity to prove that his Manchester United downfall had been caused by the circumstances surrounding Amorim rather than a decline in his ability.
Instead, the same concerns followed him to Stamford Bridge.
Garnacho struggled for consistency and struggled to establish himself as an undisputed starter. By April 2026, he had only scored just once in 22 Premier League appearances that season.
The dream of returning to his best never materialised.
Chelsea subsequently moved him on, with Aston Villa taking him on loan for the 2026/27 season with a conditional permanent-transfer arrangement reportedly worth around £42.5 million.
Surely, under Unai Emery, things would finally change?
Aston Villa has become another warning sign
Emery has built a reputation for improving players and getting struggling careers back on track. Aston Villa should therefore have represented the perfect opportunity for Garnacho to rebuild his reputation.
Instead, he currently cannot even get onto the pitch.
Villa have endured a poor beginning to the 2026/27 Premier League season and currently sit 19th after four matches. Yet even in a struggling team, Garnacho has found opportunities extremely difficult to come by.
He has accumulated only 31 competitive minutes this season and has failed to make an appearance in three consecutive matches.
The Coventry game was perhaps the most revealing moment of all.
Emery rotated heavily for the Carabao Cup, making seven changes, but Garnacho still remained on the bench for the entire 3-1 victory. The Villa manager explained that other attackers are currently ahead of him, specifically praising the likes of George Hemmings, Alysson and Ibrahim Mbaye.
That is a brutal reality for a player who once looked destined to be one of football's biggest stars.
Garnacho and the danger of modern football hype
Garnacho's story also represents a wider problem in modern football.
Young players can become superstars before they have even developed the mentality required to handle superstardom. A few spectacular goals, viral clips, social media hype and comparisons with legendary players can create enormous expectations.
But talent alone is not enough.
There is also the influence of the people surrounding young footballers. When a player becomes commercially valuable at an incredibly young age, there can be enormous pressure to maximise that value. Sometimes the advice required to build a sustainable career can become secondary to immediate fame, money and exposure.
When early hype and poor guidance combine, the consequences can be devastating.
Garnacho is still only 22. His career is certainly not mathematically over. But going from Manchester United wonderkid to Chelsea disappointment and then Aston Villa bench player in such a short period is an enormous warning sign.
The Ronaldo irony
Perhaps the biggest irony is that Garnacho's idol was always Cristiano Ronaldo.
Ronaldo was the player Garnacho wanted to emulate. He copied his celebration, admired his mentality and was repeatedly compared with him during his Manchester United breakthrough.
Yet there is one quality that separated Ronaldo from almost every other talented footballer: discipline.
Ronaldo's greatness was not built simply on spectacular ability. It was built on relentless training, professionalism, consistency, sacrifice and an obsession with improving every part of his game.
Garnacho had the talent to follow a similar path.
But talent can open the door. It cannot keep you at the top.
If Garnacho is to rescue his career, he needs to rediscover exactly what made his idol different from everyone else. The winger who once looked like Manchester United's next superstar now needs to prove that he can develop the mentality required to become one.
Otherwise, his journey from Ronaldo's potential successor to an Aston Villa bench warmer may become one of football's most painful examples of a wonderkid failing to live up to his extraordinary early promise.
