#3 Matthijs de Ligt - €85.5 million (2019)

Touted as one of the best young centre-backs in the game, Matthijs de Ligt arrived at Juventus in the summer of 2019 in a big-money move from Ajax.
After leading the Dutch club on a fairytale run to the Champions League semi-final, De Ligt was expected to hit the ground running at Juventus. However, that hasn't been the case.
Nevertheless, the young Dutchman has provided glimpses of his potential but is not yet a regular in Andrea Pirlo's side.
In 62 games for Juventus, De Ligt has scored four goals and racked up one assist, but he is clearly capable of much more.
#2 Gonzalo Higuain - €90 million (2016)

Gonzalo Higuain arrived at Juventus on a gargantuan €90 million transfer in 2016 after he became the first player to score 36 goals in a Serie A season.
Higuain's stint at the Bianconeri was a mixed bag of sorts. The 2014 FIFA World Cup finalist scored 66 goals in 149 appearances, with his goal contribution dwindling with every passing season.
After scoring only 11 times in 44 games in the 2019-20 campaign, the 33-year-old joined MLS team Inter Miami at the end of the season.
#1 Cristiano Ronaldo - €117 million (2018)

After a glorious nine-season stint at Real Madrid, Cristiano Ronaldo arrived at Juventus in the summer of 2018 on a world-record transfer for a player above the age of 30.
Suffice to say, the Portuguese maestro has hardly disappointed in his new surroundings. With a staggering 95 goals in 122 games, he has often single-handedly shouldered Juventus' attacking burden.
Despite failing to win the Champions League in three attempts with the Bianconeri, Ronaldo looks determined to help Juventus win an unprecedented tenth consecutive Scudetto.
The Bianconeri have work to do, though, as they trail leaders Inter Milan by ten points but have a game in hand. However, with Ronaldo (23 goals) eyeing his first Capocannoniere award, it may not be an insurmountable deficit to overcome as the season approaches a thrilling finale.
