At present, Spartak's archrival is CSKA Moscow, although this is a relatively recent rivalry that has only emerged after the collapse of the USSR. Seven of ten matches with the largest audience in Russian Premier League (including top three) were Spartak-CSKA derbies. Historically, the most celebrated rivalry is with Dynamo Moscow, a fiercely contested matchup which is Russia's oldest derby. Matches against Lokomotiv Moscow and Zenit Saint Petersburg attract thousands of people as well, almost always resulting in packed stadia. Upon the collapse of the Soviet Union, Spartak's rivalry with Dynamo Kyiv, one of the leaders of the USSR championship, was lost. Since Dynamo Kyiv now plays in the Ukrainian Premier League, both teams must qualify for UEFA tournaments to meet each other.
