Pep Guardiola soaked in beer as Bayern Munich celebrate third straight Bundesliga title win

Pep Guardiola signed off his three years in the Bundesliga in style, as Bayern Munich lifted a fourth straight German league title after Saturday's 3-1 win over bottom-side Hannover.

Robert Lewandowski and Mario Gotze scored the goals for Bayern before Artur Sobiech managed to pull one back, but the win was never in doubt for the hosts and their boss, departing for Manchester City.

Lewandowski gave his side the lead and in the process reached 30 league goals for the season, just after 12 minutes in to the proceedings, finishing from near the penalty spot.

He is the first player to score at least 30 goals in a season since Dieter Mueller in 1977 and became the first foreign Bundesliga top scorer to net 30 times or more as he won the title for the second time in three seasons.

Mario Gotze put aside transfer speculation, to then score two well-struck efforts, in what could also be his final Bundesliga appearance with reports suggesting he may not be a part of incoming manager Carlo Ancelotti's plans.

Sobiech scored a consolation goal, before Bayern went into full-party mode as their manager ended with an impressive 80 per cent win rate, with 82 wins in just 102 league matches in Germany.

Bayern were presented with the Bundesliga trophy after the final whistle as they became the first club to win the German league four times in a row.

This was Guardiola's 20th trophy as a coach after 14 in four years with Barcelona - and he could add to the six in three years in Munich when he signs off with a German Cup final date later this month.

The Spaniard received a standing ovation after a presentation from the sold-out Allianz Arena - before being doused in beer by his players.

"It's been a great day," said Guardiola.

"Normally games like this are unpleasant and boring, because the concentration is lacking a bit, but that was a great game with lots of intensity.

"Now we'll celebrate for a day before getting ready to play Borussia Dortmund next Saturday.

"Defending the league title is outstanding and a great compliment to these players. 

"I learned a lot, it was completely different than in Barcelona. A great experience. I'm a better coach, a little bit. It was very good for me, for my development."

Guardiola will complete a move to Manchester City in the summer, but his final game will be the German Cup final when Bayern take on Borussia Dortmund in Berlin.

Bayern finished 10 points clear of their next opponents and Guardiola will be hoping to secure a double in his final match at the club.

The Spaniard added that his one regret was not winning the champions League with Bayern, but hopes incoming manager Ancelotti can achieve that feat.

"I could not win the Champions League for my players," he said. "I'm sorry for the fans and especially for the players.
