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.
