10 most expensive flops in football history: Both Barcelona and PSG pay the price for Neymar

The historic €222 million move of Neymar Jr from Barcelona to Paris Saint-Germain in 2017 completely altered the landscape of the global transfer market. This event did not just set a new financial milestone, it initiated an era of hyper-inflation where player values are frequently inflated far beyond their actual capabilities. 

Since Neymar, European transfer windows have become increasingly saturated with "price bombs" exceeding £100 million detonated annually. However, as Flashscoremobi observes, massive wealth does not come with a guarantee of contribution. Numerous factors prevent new signings from adapting, such as recurring injuries, tactical incompatibility, poor timing, or toxic locker room relationships. 

This article will highlight 10 signings that serve as the most expensive lessons in football business history, solidified as the most expensive flops in football history.

10 most expensive flops in football history

10. Jack Grealish - Aston Villa to Manchester City (2021) - £100m

Joining the Etihad in the summer of 2021 for a then-British record fee, Grealish was expected by Pep Guardiola to bring unpredictability to the wings. At Aston Villa, he was the heart of the team, playing 213 matches, scoring 32 goals, and acting as the Premier League’s "ball-carrying king." However, upon arriving at Man City, Grealish often appeared lost in Pep’s rigid possession-based system. 

Although he was part of the historic Treble-winning 2022/23 squad, his individual contributions remained faint, with only 5 goals in 50 appearances across all competitions that season. Frequently relegated to the bench by the consistency of Phil Foden and Jeremy Doku, Grealish moved to Everton last summer on loan to fight for a position in England for World Cup 2026’s squad.

9. Antony - Ajax to Manchester United (2022) - £85m

To satisfy Erik ten Hag's tactical demands, Man United spent £85 million to bring Antony to Old Trafford at the end of the 2022 summer window. At Ajax, the Brazilian had 82 appearances, 24 goals, and 22 assists, winning 2 Eredivisie titles. However, his debut goal against Arsenal in September 2022 proved to be a "false dawn." 

Antony was quickly figured out due to his one-dimensional playstyle, lack of explosive speed, and overuse of unnecessary flair. During the 2023/24 season, he went over 20 consecutive Premier League games without a goal or assist. His meaningless "360-spin" against Sheriff in the Europa League became a symbol of this wasteful transaction. 

8. Paul Pogba - Juventus to Manchester United (2016) - £89m

One of the strangest investments in history saw United lose Pogba for free in 2012 only to buy him back for a world-record fee in 2016. At Juventus, Pogba was a world-class midfielder with 4 Scudettos, 178 appearances, 34 goals, and 40 assists. He officially returned to United in August 2016 amid expectations of a renaissance. Despite flashes of brilliance, such as his brace in the 3-2 derby comeback against Man City in 2018, Pogba never maintained consistency. Injuries and friction with the club, often fueled by agent Mino Raiola, made him a divisive figure. After 6 years, 233 games, and 39 goals, he left United for free again in 2022. 

7. Eden Hazard - Chelsea to Real Madrid (2019) - €100m

Considered the most "painful" deal for Real Madrid, Hazard arrived at the Bernabeu in June 2019 after leading Chelsea to a Europa League title with 110 goals in 352 matches. However, he debuted reportedly overweight and suffered 18 different injuries across just 4 seasons. 

Hazard famously never played a single minute of an El Clasico during his entire Madrid tenure. He made only 76 total appearances and scored a meager 7 goals, a laughable return for a €100 million investment. Hazard left Real in the summer of 2023 and retired shortly after.

6. Ousmane Dembele - Dortmund to Barcelona (2017) - €105m

Barcelona panicked after losing Neymar and spent €105 million (plus €40m in bonuses) on 20-year-old Dembele in August 2017. He had just come off a breakout season in Germany with 10 goals and 21 assists. Yet, at Camp Nou, Dembele spent more time in the infirmary than on the pitch. A lack of professional discipline and chronic hamstring issues prevented him from reaching his potential. 

Despite winning 3 La Liga titles, his legacy was marred by misses in crucial moments, such as the open goal against Liverpool in the 2019 Champions League. In 2023, he departed to join PSG, leaving Barcelona fans with a sense of bitter regret.

5. Romelu Lukaku - Inter Milan to Chelsea (2021) - €115m

In the summer of 2021, Chelsea brought back their former striker for €115 million after he led Inter to a Serie A title with 64 goals in 95 games. He was viewed as the final piece of the Premier League title puzzle. Nevertheless, after just a few months, Lukaku publicly criticized manager Thomas Tuchel’s tactics in an Italian media interview, causing a massive internal scandal. He finished the season with only 8 Premier League goals and was loaned back to Inter the following year. 

4. Antoine Griezmann - Atletico Madrid to Barcelona (2019) - €120m

In July 2019, Barcelona triggered Griezmann's €120 million release clause despite heavy opposition from Atletico. At Barca, Griezmann was forced to play out of position on the wing to accommodate Lionel Messi, which neutralized his effectiveness. After 102 games and 35 unimpressive goals, Barcelona was forced to sell him back to Atletico at a massive loss in 2021 just to clear his wages. 

3. Joao Felix - Benfica to Atletico Madrid (2019) - €126m

Dubbed the "Next Ronaldo," Felix joined Atletico for a club-record fee in July 2019 after scoring 20 goals in just 43 games for Benfica. However, Felix’s flair-heavy style clashed directly with Diego Simeone’s pragmatic, deep-defending "Cholismo" philosophy. He managed only 34 goals in 131 appearances for the club. 

Following an irreparable fallout with Simeone, Felix endured loan spells at Chelsea and Barcelona before finally making a permanent move to Chelsea in 2024 to escape the tactical prison of Madrid.

2. Philippe Coutinho – Liverpool to Barcelona (2018) – €145m

The most expensive signing in Barcelona's history turned out to be its greatest disaster. Joining in January 2018 after a "rebellion" at Liverpool (54 goals, 45 assists), Coutinho never found his rhythm at Camp Nou. The height of the irony occurred during his 2019/20 loan at Bayern Munich, where he scored twice against his parent club in a humiliating 8-2 defeat. After 106 mediocre matches and 25 goals, he was sold to Aston Villa for a mere €20 million in 2022.

1. Neymar Jr - Barcelona to PSG (2017) - €222m

Although he scored 118 goals in 173 games and won 5 Ligue 1 titles, Neymar's move is still viewed as a failure relative to the €222 million price tag. The primary objective, winning the Champions League, was never achieved. Constant injuries during the critical knockout stages made Neymar an ineffective "luxury item." He left PSG in 2023 for Al Hilal, closing a controversial era defined by unfulfilled potential and staggering financial waste.

List of the 10 most expensive flops of all time: 

Neymar Jr - €222m

Philippe Coutinho - €145m

Joao Felix - €126m

Antoine Griezmann - €120m

Romelu Lukaku - €115m

Paul Pogba - £89m

Ousmane Dembele - €105m

Eden Hazard - €100m

Antony - £85m

Jack Grealish - £100m

To this day, the waste of over £400 million on the attacking trio of Griezmann, Dembele, and Coutinho continues to haunt Barcelona, forcing the club to shoulder massive debts that remain unresolved. In the near future, these 3 will likely remain permanent fixtures in the list of the most forgettable and most expensive flops in football history on Flashscoremobi.com.
