Crazy scenes as fans invade pitch before full-time as Bayer Leverkusen clinch first-ever Bundesliga title

There were crazy scenes in Germany as fans invaded the pitch BEFORE full-time as Bayer Leverkusen clinched the Bundesliga title.

Bayer Leverkusen's surge to the Bundesliga title has been the story of the season, and on Sunday they finally got their hands on the trophy for the first time in the club's history.

Xabi Alonso's side only needed to beat Werder Bremen on the final day of the season to officially become champions, and they did it in style with a 5-0 victory.

Victor Boniface and Granit Xhaka put the home side in control, before wonderkid Florian Wirtz scored a second half hat-trick - his first in senior football - to send supporters in the stands into raptures.

The victory extended Leverkusen's unbeaten start to the season to 29 matches, a new Bundesliga record.

Leverkusen have now gone 43 games unbeaten, the longest unbeaten run in European football history.

But Leverkusen fans didn't care about that - the most important thing was clinching the club's first Bundesliga title, and they were ready to celebrate in style.

As the match entered the final 10 minutes, supporters started jumping down from the stand to stand behind the pitch-side advertising boards.

When Wirtz scored his second goal in the 83rd minute, hundreds of fans spilled onto the pitch, knocking over the boardings and causing mayhem.

Wirtz and his teammates pleaded with the fans to leave the pitch, fearful the match could be abandoned in the final moments.

The match resumed in a cloud of red pyrotechnic smoke, and when Wirtz completed his hat-trick in the 90th minute even more supporters stormed the field and began to celebrate. The limbs were incredible.

The referee didn't even bother to restart the match, and instead blew his final whistle to make Leverkusen's monumental achievement official.

Thousand of fans poured onto the pitch to mob their heroes, with the likes of Jeremie Frimpong and Wirtz hugging everyone in sight and taking plenty of photos.

After so many near-misses and heart-breaks over the years, Leverkusen have ended Bayern's strangle-hold on German football to an end and done it playing some extraordinary football.

What a story.
