Bayern Munich started the defence of their Bundesliga title in ominous fashion as a Serge Gnabry hat-trick helped them to a stunning 8-0 win over Schalke at the Allianz Arena on Friday.

A mere 26 days after winning the Champions League, Hansi Flick's side showed no signs of tiredness and powered into a fourth-minute lead thanks to Gnabry's superb strike.
