Bayern 5-1 Arsenal: Welcome to the house of fünf

Arsenal are preparing to beat Bayern Munich 3-0 in the second leg of their Champions League last-16 tie after being easily beaten 5-1 in their first.

The Gunners were pretty much dire for most of the game, but headed into half-time level after Alexis Sanchez cancelled out Arjen Robben’s opener.

Three goals in ten second-half minutes from Robert Lewandowski and Thiago Alcantara, who scored twice, made the tie almost a formality.

Thomas Muller then compounded the Gunners’ woes at the Allianz Arena, the substitute adding a fifth two minutes from time.

Wenger had opted to field David Ospina rather than Petr Cech in goal, while Alex Oxlade-Chamberlain and Alex Iwobi were tasked with dropping back into a four-man midfield when Arsenal were defending.

Wenger’s goalkeeping decision made no impact on the opening goal as Robben moved inside unchallenged before bending a superb effort past the desperate dive of Ospina.

Bayern dominated possession for much of the opening half as Arsenal remained boxed in defensively, although Sanchez won a free-kick on the edge of the penalty area after bursting forward at pace and being fouled by Mats Hummels.

Ozil hit a tame free-kick, which Manuel Neuer made hard work of, but the Germany goalkeeper was equal to Sanchez’s penalty after referee Milorad Mazic pointed to the spot having adjudged that Lewandowski had fouled Laurent Koscielny.

Although he missed the resulting spot-kick, Sanchez recovered and after fluffing his lines again managed to tuck away the equaliser.

The Gunners were growing in confidence and, after Ozil and Sanchez combined, the latter slipped in Oxlade-Chamberlain whose cross dropped to Granit Xhaka, but his firm shot was straight at Neuer.

Lewandowski then passed up a glorious chance to make amends for conceding the penalty as the striker could only head a David Alaba cross over from in front of goal.

While the hosts remained a threat throughout the first half, Arsenal were also more involved as an attacking force and Ozil bought a smart stop out of Neuer on the stroke of half-time.

The game and the tie arguably hinged on an incident on 49 minutes when Koscielny over-stretched to make a clearance and was forced off, with Gabriel on in his place.

Less than 15 minutes later and Arsenal were three goals behind as Lewandowski nodded home Philipp Lahm’s cross before flicking a pass into the path of Thiago, who slotted home coolly.

Arsenal were rocked and could have conceded again as Ospina rushed off his line to harry Lewandowski, who turned a shot against the bar before Robben’s rebound was deflected behind.

The Colombian goalkeeper atoned for his error by making a superb point-blank save from the busy forward, but he was soon beaten again as Thiago’s strike came off Xhaka and into the net.

Still chances kept coming Bayern’s way, Ospina getting down well to push Vidal’s low drive wide on the post before tipping Douglas Costa’s strike behind.

Muller came off the bench to a heroes welcome as Lewandowski made way, and despite having only four minutes to make an impact he did just that as he converted the fifth as Bayern beat Arsenal 5-1 for the second meeting in succession.
