Fabián Cornelio Balbuena González (born 23 August 1991) is a Paraguayan professional footballer who plays as a centre-back for Russian Premier League club Dynamo Moscow and the Paraguay national team.

[citation needed] On 16 February 2016, Balbuena moved abroad for the first time in his career after agreeing to a three-year deal with Série A side Corinthians.

[6] He made his debut for the club nine days later by starting in a 1–1 Campeonato Paulista away draw against São Bento, and scored his first goal on 19 March in a 4–0 home routing of Linense for the same competition.

[10] On 18 October 2020, Balbuena scored West Ham's first goal as they overturned a 3–0 deficit with eight minutes remaining to draw at London rivals Tottenham Hotspur.

[11] The following 24 April, he was sent off in a 1–0 home loss to another capital team, Chelsea, for catching Ben Chilwell when making a clearance; the decision was criticised by manager David Moyes and various pundits.

[15] On 10 July 2022, Balbuena suspended his contract with Dynamo Moscow for the 2022–23 season, having taken advantage of the FIFA ruling relating to the Russian invasion of Ukraine.

[22] He made his first competitive appearance at the latter in the final group game, a 1–0 loss to hosts the United States in which he was substituted at half time for attacker Juan Iturbe.
