Pep Guardiola had plenty to celebrate after guiding his Bayern Munich team to the Bundesliga title.
Sure, he may have missed out on the chance to win the Champions League in Bavaria before he departs to take over Manchester City, but it's not been all bad at the Allianz Arena.
The former Barcelona coach won three straight titles in Germany and they lost just twice this season, plus the 45-year-old scooped the DFB-Pokal Cup in 2014. Yep, there was plenty to celebrate.
That was until Xabi Alonso came along.
Pep was celebrating in front of a jubilant home crowd at the Allianz Arena following their 3-1 win over Hannover to end the season.
As is tradition in Germany, the steins of beer were soon brought out and being thrown around by the Bayern team and their coaching staff.
Pep was revelling in the moment and chasing around a member of his backroom team when...POW! right in the kisser! Alonso struck and soaked his manager from head to toe. Lucky for the Spaniard that Guardiola won't be his manager for much longer, otherwise he may be in trouble.
You can check out the video of the hilarious incident below.
Next up for Guardiola is a trip to Manchester City, and he'll have quite the task on his hands to turn the Citizens into a major European force.
Although they made the Champions League semi-finals this year it looks as though they're only going to scrape a qualification spot for next season's competition by the skin of their teeth, while their domestic title hopes are long since gone.
Still, at least he's not at risk of drowning in beer in Manchester. So, you know, swings and roundabouts.
