You will have to excuse Jürgen Klopp if he is a little bit overexcited. He is normally excited, as is everyone on his Borussia Dortmund team. The joy and enthusiasm they play with, and then celebrate with, is why they are one of the most endearing teams in the world. Toss in the fact that they are really good too and, well, all is well in Kloppland.
On Saturday, Dortmund defeated Borussia Mönchengladbach, 2-0, to clinch their second consecutive Bundesliga title and that right there is a reason to go from regular Klopp-like overexcitement to crazy overexcitement. So when Shinji Kagawa scored Dortmund's second goal of the match to basically wrap up the match and title, Klopp sprinted down to the corner to not just huge Kagawa, but lift him up. It was the best. Klopp is the best. Everyone wants to live in Kloppland.
If you're a good person then you will imagine Kagawa saying, "wheeeeeeeee!" when Klopp lifts him.
