5. Arthur Melo to Juventus (€80.6m – September 2020)

One of Juventus’ more questionable transfer moves saw them pay well over the odds for Arthur Melo in 2020 as Barcelona received a whopping €80.6m for the defensive midfielder, while Miralem Pjanic moved the other way.

4. Dusan Vlahovic to Juventus (€83.5m – January 2022)

Dusan Vlahovic has proven a good signing for Juventus in terms of adding quality to their squad even if he cost them €83.5m as a 22-year-old late in the 2022 January window.

3. Matthijs de Ligt to Juventus (€85.5m – July 2019)

It isn’t often that a teenaged centre-back demands a transfer fee of €85.5m but Ajax Amsterdam felt they had a gem in Matthijs de Ligt and Juventus agreed.

2. Gonzalo Higuain to Juventus (€90m – July 2016)

Juventus had no reason to believe that their €90m investment in proven star striker Gonzalo Higuain wasn’t quite going to pan out to their liking when they signed him from Napoli fresh off a Serie A season that saw his score 36 league goals in 35 games.

1. Cristiano Ronaldo to Juventus (€117m – July 2018)

Cristiano Ronaldo‘s blockbuster move to Juventus in 2018 certainly had its doubters but despite joining the club at 33 and costing them €117m, CR7’s time in Turin was memorable if brief.

He was player of the year in all three seasons he played at Juventus and helped the club to two Serie A titles in his stint.
