Werder Bremen and Bayern ultras start huge pyrotechnic show using hundreds of flares and fireworks in season-opening Bundesliga clash as Harry Kane makes his league debut

The Englishman scored as he made his German top-flight debut against Bremen with Bayern traveling to the Weserstadion on the eve of the weekend.

Supporters at opposite ends of the stadium lit a unison of pyrotechnics with one group using bright white explosives and the other striking up red flares.

Footage shows a huge array of white fireworks being set off in the lower tier of one stand as the crowd, obscured from view beneath a blanket of smoke bounce up and down.

Chants can be heard echoing around the venue while pops of flares continue to sound and giant flags are waved in the midst of the stand.

However there appears to be no intervention from any officials with the fans eventually allowing their devices to run out of gunpowder.

The red flares in the away section at the other end of the stadium are equally impressive with Bayern supporters responding in equal message.

Smoke again fills up that part of the
