#4 Kevin de Bruyne
Market Value in July 2017: €65 million
Current market value: €150 million
Arguably the best midfielder in the world right now. The Belgium international was phenomenal for Manchester City last season and also guided his national team to a third-place finish in the 2018 World Cup.
The 27-year-old scored 10 goals and assisted 20 more for Manchester City across all competitions last season. City dominated the Premier League last campaign and de Bruyne played an integral part in their title win.
He scored a goal and assisted two more for Belgium at the World Cup, while his market value has drastically increased - by €85 million (130.8%) in the past 12 months.
