Ukraine's Shakhtar Donetsk beat Belarus's Bate Borisov 7-0 in an away game in the Champions League's Group H on October 21.
Shakhtar's Brazilian striker Luiz Adriano equalled Barcelona's Lionel Messi as the only players to hit five goals in a Champions League game.
Shakhtar's 6-0 halftime lead also set a new record for Europe's elite club competition.
The Ukrainians are now second in the group on five points.
Shakhtar's win comes a day after the team's Donbas Arena stadium suffered serious blast damage from shelling October 20 despite a cease-fire agreed between the Ukraine government and Russian-backed separatists.
The modern, 52,000-seat venue hosted five matches at Euro 2012 and regular Champions League games.
Shakhtar have moved their headquarters from war-torn Donetsk to Kyiv, with home games being played in the western city of Lviv.
