Paris, November 5

Arsenal’s hopes of reaching the Champions League knockout phase were left hanging by a thread on Wednesday after they were thrashed 5-1 by Bayern Munich, while Chelsea revived their faltering campaign with a nervy 2-1 victory over Dynamo Kiev.

Zenit St Petersburg became the third team to reach the last 16 of the game as the Russian champions maintained their 100 per cent record with a 2-0 win at Lyon, while Barcelona edged closer towards qualification after beating BATE Borisov 3-0.

Bayern’s unbeaten start to the season was ended by a 2-0 defeat at Arsenal a fortnight ago but Pep Guardiola’s side exacted revenge and then some at the Allianz Arena. Robert Lewandowski headed Bayern into a 10th-minute lead as Arsenal’s attempt to catch the Poland striker offside backfired. Thomas Mueller added a second just before the half hour as his shot deflected off Per Mertesacker and crept in at Petr Cech’s near post.

Substitute Arjen Robben then smashed home an Alaba cutback early in the second half while Olivier Giroud’s acrobatic effort pulled one back for the Gunners. But Mueller compounded Arsenal’s misery a minute from time to condemn the Gunners to their joint-heaviest European defeat.

Meanwhile, beleaguered Chelsea coach Jose Mourinho was a much-relieved man after Willian helped steer the Blues past their Ukrainian opponents.

Chelsea took a first-half lead at Stamford Bridge when Willian’s right-wing cross was headed into his own net by Aleksandar Dragovic, only for the Austrian to atone with a 78th-minute equaliser. But Willian curled in a superb free-kick seven minutes from time to hand the hosts all three points and bump them up to second in Group G, two points above Kiev.

Porto remain top of the section after easing to a 3-1 win away to bottom side.
