Arsenal equalled the record Champions League victory with a 7-0 thumping of Slavia Prague on Tuesday as Manchester United also took a major step towards a place in the last 16 with a 4-2 win at Dynamo Kiev.
Arsenal made it three wins out of three as they matched the record set by Juventus against Olympiakos in 2003 with a breathtaking display.
Two goals each from Cesc Fabregas and Theo Walcott, his first in Europe's premier club competition, one apiece by Aleksandr Hleb and Nicklas Bendtner as well as a David Hubacek own-goal left Arsenal top of Group H with a maximum nine points.
Double UEFA Cup winners Sevilla are second with six after first-half goals from Frederic Kanoute and Luis Fabiano helped them to a 2-1 home success against Steaua Bucharest.
United also maintained their perfect start in Group F after Cristiano Ronaldo scored a brace and Wayne Rooney and Rio Ferdinand added a goal each against Kiev, who gained some consolation thanks to Diogo Rincon and Ismael Bangoura.
Roma move to second
Roma moved into second position with a 2-1 defeat of Sporting Lisbon at the Olympic stadium, with Montenegro striker Mirko Vucinic scoring a 70th-minute winner after coming on as a first-half substitute for injured Francesco Totti.
Juan gave Roma a 15th-minute lead, Brazilian Liedson equalised shortly afterwards and their countryman Mancini missed a 49th-minute penalty for the home side before Vucinic capped a dazzling solo run with a rising shot into the top corner.
A goalless draw at Ibrox left Rangers and Barcelona joint top of Group E with seven points, while Lyon kept alive their hopes of finishing at least third and securing a UEFA Cup spot after the winter break with a 2-0 win at VfB Stuttgart.
It was one-way traffic in north London after Fabregas drilled in a powerful shot in the fifth minute to send Arsenal on their way on a memorable evening for Arsene Wenger's side.
Hubacek turned into his own net and Belarus midfielder Hleb put his name on the scoresheet after Walcott scored his first and Arsenal's third. Walcott made it 5-0 and Fabregas added the sixth while Bendtner's tap-in completed the rout in the 89th minute.
In Kiev, Ferdinand headed United into an early lead and Rooney made it 2-0 in the 18th minute after good work by Ronaldo and Wes Brown.
Rincon pulled one back for Kiev before Ronaldo struck twice to put the game beyond the home team, who salvaged some pride through Guinea striker Bangoura.
In the afternoon kick-off, Inter Milan fought back to beat CSKA Moscow 2-1 in the Russian capital and go top of Group G a point ahead of Fenerbahce, who were held to a 0-0 draw at PSV Eindhoven.
