Leonardo Julián Balerdi Rosa (born 26 January 1999) is an Argentine professional footballer who plays as a centre back for Ligue 1 club Marseille and the Argentina national team.

Balerdi made his debut for Boca Juniors in the Argentine Primera División starting against Club Atlético Huracán on 27 August 2018.

Although only appearing 5 times for Boca Juniors (a total of 450 minutes on the pitch ), Balerdi's performances took Argentinian football by storm and he has rapidly been hailed as Argentina's best upcoming defender.

In January 2019, Balerdi agreed to a four and a half year contract with Borussia Dortmund.

According to several Argentine reports, Dortmund has agreed to pay €15 million for the central defender.

An additional €2 million might need to be paid due to agreed add-ons.

Balerdi made his Dortmund and Bundesliga debut on 7 December 2019 against Fortuna Düsseldorf coming onto the pitch as a substitute in the 78th minute.

He made his Argentina national team debut on 10 September 2019 in a friendly against Mexico.

In July 2020, Balerdi signed with Olympique de Marseille on a one-year loan deal with an option to buy for €15 million.

On 3 July 2021, Balerdi joined Marseille on a permanent basis, signing a five-year contract with the club.

Balerdi holds both Argentine and Italian nationality.
