Bayern Munich stars said a bulked-up mentality was key to retaining the Bundesliga title with four games to spare, while also destroying the league season scoring record by netting 109 so far.

A 4-2 home win over VfB Stuttgart on Sunday sealed a second straight crown, with just one game lost in the league this term.

After the game, players wore special T-shirts with an image of a cockatoo, which became the team's official mascot after a porcelain version was taken from a restaurant during a party for last season's Bundesliga title.

Celebrations were slightly muted on Sunday given title wins are now commonplace in Munich and the trophy presentation is expected on the final day of the season against Cologne on May 16. There is also a German Cup semi-final at Bayer Leverkusen on Wednesday and a Champions League semi-final against Paris Saint-Germain to come.

"It is a great moment for us," playmaker Jamal Musiala told DAZN.

"I think from the first friendly, we said our mentality had to take a step forward. This is a big lesson for us and we have to take this into the future."

"We are having a proper big party after the last game. Now not a lot is planned."

The team took in the applause from the packed stands and executives in the stand drank beer and wine, but otherwise there was little razzmatazz given the tasks ahead.

Germany captain Joshua Kimmich, who wonn his 10th league title individually with Bayern, said: "It is very special. It has been a very, very good Bundesliga season.

The way we did it, we were very consistent...and we haven't achieved that form so often. I hope 10 more titles come on top of this."
