It's a packed Allianz Arena. The players have done their high-fives and Dortmund get us under way. 

Forget your pyrotechnics and your supersized banners... Bayern Munich's welcome to the Allianz Arena includes one of Bavaria's best horn sections.

The players are in the tunnel and we are approaching kick-off. It should be an electric atmosphere.

There has been plenty of other Euro action elsewhere today. 

Inter Milan have taken over at the top of Serie A - for the time being at least.

A 1-1 draw at Sampdoria was enough for Roberto Mancini's side to replace Fiorentina at the head of the Italian League.

However, Fiorentina play Atalanta this evening (19:45 BST) so it could be a short-lived lead.

Roma have gone third with a 4-2 win at Palermo.

In the Netherlands, PSV Eindhoven stepped up their title defence by winning 2-1 at leaders Ajax as Frank de Boer's side lost for the first time.

A wee reminder of the formidable Bundesliga form of Bayern striker Robert Lewandowski and Dortmund forward Pierre Emerick Aubameyang. Lewandoski has 10 goals in his last three games in all competitions, while Aubameyang is the first player to score in the opening seven Bundesliga games.

It's been a busy day already across Europe with some tasty appetizers in the Bundesliga before the main event in Munich.

Even before kick-off it's good news for the top two with third-placed Schalke losing 3-0 at home to Cologne with just a few minutes to go. Former Blackburn loan striker Anthony Modeste got Cologne's opening goal.

Fourth-placed Hertha Berlin have beaten Hamburg 3-0, while in the clash of the two clubs who lost to Manchester's finest in the Champions League in mid-week, Borussia Monchengladbach beat Wolfsburg 2-0. 

So with that smorgasbord on offer, let's keep it Euro. Can Thomas Tuchel's Dortmund derail the Bayern juggernaut? Who will be on top on as the sharp shooters go head to head? 

Can Juve get their domestic season up and running and can Real Madrid keep their noses in front of Atletico in La Liga later on?

After their shocking start to last season under former boss Jurgen Klopp, Dortmund are back on song with Thomas Tuchel now in charge. Neither side have lost this season so we are all set for a Der Klassiker of epic proportions on what promises to be a day where even the Euro-sceptics amongst you may start salivating.

Yep, it's only a small matter of the biggest game in Bundesliga football for Pep and his team of Bayern Munich boozers. It's the leaders versus second-placed Borrusia Dortmund, who have made a brilliant start to the season with five wins and two draws. No worries, though. Bayern are seven wins from seven. 

"Barmaid, another 11 jugs over here, please." 

Can you imagine the furore in England if Manchester United Louis van Gaal was seen warming up for a derby clash with Manchester City by getting the steins in down the city's Northern Quarter? 

But such is the tranquillity in Pep Guardiola's world that nothing seems likely to put the Bayern Munich boss off course!
