Holders Barcelona celebrated qualifying for the last 16 of the Champions League with another stunning display on Tuesday, Luis Suarez and Lionel Messi both scoring twice in a 6-1 win against Roma. The Catalans and Bayern Munich both secured their places in the knockout draw and demonstrated once again why they are surely the best teams in Europe just now, with Bayern crushing Olympiakos 4-0 at the Allianz Arena.
Barcelona discovered they had qualified from Group E before they had kicked a ball at the Camp Nou, the 1-1 draw between BATE Borisov and Bayer Leverkusen in Belarus ensuring their passage.
Fresh from crushing eternal rivals Real Madrid 4-0 at the weekend, they then produced a performance that the Italians could not live with to secure top spot in the section.
Dani Alves set up Suarez to tap in the opener before Messi, in his first start since returning from injury, made it two at the end of a superb move involving Neymar and Suarez.
Suarez struck again just before the interval with a sweet volley and the rout continued in the second half as Neymar, Suarez and Messi all combined to give Gerard Pique a tap-in.
Neymar and Suarez then helped tee up Messi to get his second and Barca's fifth on the hour and Adriano crashed in the sixth after Neymar's penalty had been saved by Wojciech Szczesny.
Roma's misery was compounded when Edin Dzeko had a late penalty saved by Marc Andre ter Stegen, although Dzeko did pull one back with the last kick of the game.
BATE opened the scoring in the second minute in Belarus through Mikhail Gordeichuk, but Admir Mehmedi equalised in the second half for Leverkusen.
While Bayern secured top spot in Group F, Arsenal kept their hopes alive by beating Dinamo Zagreb 3-0 at the Emirates Stadium.
Mesut Ozil headed the Premier League side ahead and Alexis Sanchez added a brace, meaning the Gunners can still qualify for the last 16, provided they win at Olympiakos next month by at least a two-goal margin or by winning by a one-goal margin having scored three or more goals.
The other game in Group G saw Dynamo Kiev win 2-0 at Porto with Andriy Yarmolenko netting a first-half penalty before Derlis Gonzalez wrapped up the points.
