Aleksei Berezutski

He began his professional career in 1999 at the age of 17 at Torpedo Moscow, graduating from the club's famed academy. He spent the rest of his playing career at CSKA Moscow. He mostly played as a central defender but he could play as fullback, wingback, defensive midfielder or even as a winger. He scored CSKA Moscow's first goal as they came from behind to win the 2005 UEFA Cup Final. Following his side's Champions League match against Manchester United at Old Trafford on 3 November 2009, Berezutsky (along with colleague Sergei Ignashevich) tested positive for the banned substance sudafed. The two players were provisionally suspended until the case was heard by the European governing body's disciplinary committee on 17 December, according to a UEFA statement. It was later revealed that they had taken a cold medicine which had not been reported, and both players were suspended for 1 game, which was applied retroactively. He officially announced his retirement from playing on 21 July 2018.

Berezutski was a Russia national football team regular, making 32 appearances since 2003. Aleksei was selected Russia's captain for the 0–3 friendly defeat against Romania, though it was speculated that Hiddink only gave him the captain's armband so he could differentiate between Aleksei and Vasili. He was confirmed for the finalized UEFA Euro 2012 squad on 25 May 2012. On 7 March 2018, he officially retired from international football.

On 3 January 2019, Aleksei and his twin brother Vasili joined Dutch club Vitesse as assistant coaches to Leonid Slutsky, who trained them with CSKA and the national team. In February 2021, he joined Vasili as an assistant to Viktor Goncharenko back at CSKA Moscow. In April 2021, Goncharenko moved to FC Krasnodar, with Vasili following him as an assistant. Aleksei remained at CSKA to assist the new manager (and former CSKA teammate) Ivica Olić. On 15 June 2021, Berezutski was announced as CSKA Moscow caretaker manager after Ivica Olić left his role as manager by mutual consent. A little over a month later, 19 July 2021, Berezutski was confirmed as CSKA's new permanent head coach. On 25 March 2022, Berezutski was named Russian Premier League's coach of the month after CSKA won four games in the preceding month, extending their winning streak to 6 league matches overall. On 15 June 2022, he left CSKA by mutual consent. On 6 June 2024, Berezutski returned to CSKA as an assistant manager to Marko Nikolić. He left CSKA on 12 January 2026.

Aleksei started to play football in sport school Smena in Moscow, before moving to Torpedo's academy. He is married and has a daughter named Alyona. His identical twin brother, Vasili, is also a professional footballer, coming through the Torpedo academy alongside his brother, who he played with at CSKA too.
