Eyebrows were raised when Arsenal agreed to play Bayern Munich in a pre-season friendly this summer.Why on earth would they deliberately choose to play against the one team that *always* seem to beat them every season? Surely it would only dent their confidence heading into the 2017-18 campaign.However, Arsene Wenger proved that taking on Bayern was, in fact, a great decision - by masterminding a rare victory over the German giants.Robert Lewandowski put Bayern 1-0 up in the ninth minute at the Shanghai Stadium, converting past Petr Cech from the penalty spot.It looked set to be a long afternoon for the Gunners.However, no further goals were scored until the final minute of stoppage time, when Alex Iwobi popped up to score the equalising goal and forcing penalties.David Alaba, Renato Sanches and Juan Bernat all missed for Bayern, while successfully converted spot-kicks from Aaron Ramsey, Nacho Monreal and Iwobi sealed a morale-boosting victory for Wenger’s men.Watch the shoot-out here...

Arsenal still got trolled by Bayern

However, Bayern Munich’s Twitter account still found a way to troll Arsenal.

“Well, you can't win them all! 😅“ Bayern tweeted, before adding that Iwobi had sent the match to penalties.

That’s a dig.

Here’s how Arsenal fans reacted to the tweet…

Bayern then wished Arsenal good luck for the season

However, the people behind Bayern’s Twitter account then made amends by wishing Arsenal good luck for the forthcoming season.

Classy touch.

Arsenal fans appreciated that…
