Bayern Munich officials have reportedly been left "puzzled" following Arsenal manager Arsene Wenger's alleged failure to shake hands with Pep Guardiola.

It has been reported that the Frenchman did not shake his counterpart's hand before or after Arsenal's 2-0 defeat to Bayern in their Champions League clash at the Emirates on Wednesday.

According to The Mirror, German journalist Rafael Honigstein of the Suddeutsche Zeitung has claimed that Bayern officials are baffled by Wenger's actions.

Toni Kroos and Thomas Muller found the back of the net during the first leg of the round-of-16 tie, which included a missed penalty for both teams and a red card for Arsenal goalkeeper Wojciech Szczesny.
