Transfermarkt, the renowned website specializing in player analytics, transfers, and market valuations, celebrated its 25th anniversary by publishing a special report highlighting football stars who experienced the largest increase in market value over a single season in the history of modern football.

Mohamed Salah: A Historic €115 Million Surge
Egyptian superstar Mohamed Salah topped this global list after a phenomenal performance during the 2017–2018 season with Liverpool. Having joined from AS Roma with a market value of just €35 million, Salah stunned the world with an incredible all-around season.
The “Egyptian King” scored 44 goals and provided 16 assists in 52 appearances, which saw his market value skyrocket to €150 million — an increase of €115 million in a single season. This remains the largest jump ever recorded on Transfermarkt, putting him ahead of all other global stars.

Lamine Yamal: The Future Shines Twice
The report also reflected current events, with rising Barcelona star Lamine Yamal appearing twice on the list — in second and third place. During the 2024–2025 season, his market value surged by €110 million, reaching €200 million, making him the most valuable player in the world today.
He also claimed third place for the 2023–2024 season, with a €90 million rise — matching the increase achieved by Harry Kane in the 2017–2018 season.

Kane, Mbappé, and De Bruyne in the Top Ten
Harry Kane, former Tottenham and current Bayern Munich striker, came fourth with a market value jump of €90 million in one season, reaching €150 million.
French star Kylian Mbappé made two appearances on the list — first, with an €85 million increase when he moved from Monaco to Paris Saint-Germain in 2017–2018, and again in his first full season with PSG, when his value rose by €80 million, reaching €180 million.
Other big names included Jadon Sancho, who shined with Borussia Dortmund in 2018–2019, Kevin De Bruyne, who had one of his best seasons with Manchester City, as well as Neymar and Frenkie de Jong, who caught global attention with Ajax.
