​Three things we learned from Bundesliga Saturday Afternoon Matchday 1 – Elversberg’s welcome to the Bundesliga, An unwelcome reunion and 19 goals in five gamesBayern Munich and Stuttgart opened the Bundesliga season last night with a 5-1 win for Vincent Kompany’s side, but today was the start of the real Bundesliga with 10 teams kicking off their seasons. In action this afternoon were debutants Elversberg vs Bayer Leverkusen, Köln hosted Hoffenheim, RB Leipzig played Borussia Mönchengladbach, Union Berlin were against Eintracht Frankfurt, and Mainz were against newly promoted Paderborn.Here are the three things we learnt:Elversberg pass their ‘Welcome to the Bundesliga’ test:There aren’t many harder games than hosting Bayer Leverkusen in your maiden top-flight campaign opener, but Elversberg have shocked everyone as they held off a resurgent Werkself to win their first-ever game 3-2.Not only was the result itself impressive, but the manner in which the Saarland side did it too. Within 10 minutes, Elversberg were 2-0 up thanks to goals from Lukas Petkov and Cole Campbell (former Borussia Dortmund winger). Leverkusen were the dominant side throughout the game, but were not able to produce anything to show for it. Just after the break, Elversberg would then make it 3-0 through David Mokwa.

So what better way for him to make his Bundesliga debut for Leipzig than against his former side?In the first half, Borussia Mönchengladbach were the better side but undeservedly went down 1-0 thanks to a Ridle Baku goal in the 26th minute. However, it was in the second half that the wheels came off and Antonio Nusa doubled Leipzig’s lead just after the break. Then, in the 66th minute, Leipzig made it 3-0 thanks to who else but Reitz. This storyline aside, with the doubts surrounding head coach Martin Demichelis and his credentials as Leipzig head coach, this was a strong way to kick off their Bundesliga campaign, but there will be much more difficult games on the horizon. While this game also saw the return of Christop
