Real Madrid star Rodrygo Silva de Goes started his career at Santos before Real Madrid signed him. At the time, he was worth €10 million. However, the increase in his market value since he joined the club has been phenomenal.
This is due to the Brazilian star's remarkable improvement. In the season in which he joined the Spanish La Liga side, his market value was €50 million. The following season, it fell to €45 million and then €40 million after a bedding-in period.
However, since 2022, his market value has been on the rise. After increasing to €60 million in 2022, the former Santos star is now worth €80 million, and this is bound to increase as he continues to develop. This season, he has scored 16 goals and had 11 assists.
In the case of Jack Grealish, the Englishman started his professional career with Aston Villa, where he became an in-demand player. 
However, Manchester City was able to sign him for a record fee of €117 million.
At the start of his Manchester City career, he was unable to break into the team due to competition and adaptability. However, he is now a regular on the team.
As of 2016, Jack Grealish's market value was €4.5 million. This continued to increase on a seasonal basis when he was at Aston Villa. When he made the move to Manchester City, his market value reached an all-time high of €100 million. However, after a poor start to his time in Manchester, his market value has fallen to €70 million.
Another star whose market value increase has been astonishing is AC Milan star Rafael Leao. The Portuguese star started his professional career with Sporting Lisbon. At that time, he was worth €6 million. After moving to AC Milan in 2019, his market value increased to €15 million.
Since then, his market value has continued to evolve impressively. Last year, it rose to its highest point of €85 million; however, it has fallen to €80 million in 2023.
