Brilliant by Arjen Robben. The Dutchman slips the ball inside to Phillip Lahm, he receives it back from the German's back heel, and Robben's ferocious strike is well tipped over by goalkeeper Roman Weidenfeller.

I hope for Dortmund's sake that isn't a sign of things to come.

A cagey opening in the first few minutes as both sides look to feel each other out. With Dortmund's fragile confidence an early goal really could open the floodgates.

Dortmund could probably do with him having a nightmare.....

And we are off........

The players appear to be getting on as well. Must be just in the boardroom where the two clubs dislike each other.

The teams are coming out at the Allianz Arena and both sets of fans are absolutely bouncing. Nice to see Dortmund boss Jurgen Klopp give former striker Robert Lewandowski a hug as well..

While Dortmund could yet recover from their torrid start to the campaign, their Bundesliga beginning got me thinking about dramatic falls from grace in sport.

Can you think of anyone who has suffered a dramatic decline in their sport. It can be an individual, a team or even an animal. Let us know via #bbceurofooty.

Your contribution would be much appreciated - or else you have to have more of me.....

Marco Reus is at least attempting to play down the speculation about his future.

"There are a lot of people talking about my future," said Reus, 25. "Other people are thinking more about my future more than me".

Sadly for Dortmund though, you fear if Bayern want the midfielder they will get him.

There is a little bit extra riding on tonight's opener as well - with internal relations between Bayern and Borussia frosty to say the least.

Not satisfied with taking Dortmund's best players off them in recent seasons - notably Mario Gotze and Robert Lewandowski - they appear to be targeting Die Schwarzgelben's Marco Reus now.

Bayern chief executive Karl-Heinz Rummenigge is not the flavour of the month at Dortmund after making his interest public.

In fact, the traditional lunch between the bosses of the rivals has been scrapped this afternoon.......

Bayern Munich: Neuer, Alonso, Benatia, Lewandowski, Robben, Boateng, Bernat, Gotze, Lahm, Muller, Alaba. Subs: Zingerle, Dante, Ribery, Shaqiri, Rafinha, Pizarro, Rode.

Borussia Dortmund: Weidenfeller; Piszczek, Sokratis, Hummels, Durm; Bender, Kehl; Mkhitaryan, Kagawa, Reus; Aubameyang. Subs: Langerak, Subotic, Grosskreutz, Ginter, Gundogan, Immobile, Ramos.

Few would have predicted Dortmund's fall from grace so far this season.

Klopp's side were runners up last season, won the Bundesliga in 2011 and lifted the domestic double in 2012. Now they are struggling to win a league game.

There is a little bit of good news for them, as they top their Champions League group with three wins form three games.

Today's opponents Bayern also have a 100 per cent Champions League record, but they are flying high unbeaten at the top of the league too.

There is a very tasty Bundesliga clash that is going to be our focus before we switch to La Liga though as Bayern Munich entertain Borussia Dortmund.

A match between title-challengers right? Perhaps not this season with Dortmund in 16th and without a win six. For boss Jurgen Klopp, 2014/15 has been an absolute nightmare.

This rivalry has recent history though. Rip up the form book because Dortmund will be out to wipe the smiles of Bayern's faces.

Italian Serie A

In Italy Rafael Benitez's Napoli went third in Serie A with victory over Roma.

Gonzalo Higuain gave the hosts an early lead with an acrobatic volley from six yards following Lorenzo Insigne's deflected shot.

Roma, who started the day as joint leaders with Juventus, had chances but Alessandro Florenzi shot wide and also had a shot saved by Rafael Cabral.

But Jose Callejon sealed the win when he collected Higuain's pass and fired past goalkeeper Morgan De Sanctis.

Before we focus on what is to come, let's have a quick recap on what has already happened in Europe this weekend.

Real Madrid temporarily move to the top of La Liga with a crushing 4-0 win at Granada. Cristiano Ronaldo - of course - James Rodriguez and Karim Benzema were on target.

That lead may not last long mind.

Good evening. Hola. Guten Abend.

As you've just been told, Barcelona v Celta Vigo will be the centre of our attention later this evening with the Catalans looking to return to the top of the pile in La Liga.

But before that we will start with a live text commentary from Munich, where Bundesliga champions and leaders Bayern look to deepen Borussia Dortmund's already considerable woes.

Add to that, reactions and results from elsewhere in Europe and we have a busy night ahead. Forget the X-Factor!

Yes. After months of hype, tonight could be the night that Lionel Messi fires himself to the top of La Liga's all-time goal-scorers' list.

Messi has scored 250 goals in 284 appearances for Barcelona and is one behind Telmo Zarra's record for Athletic Bilbao in the 1940s and 1950s.

Can he get the two he needs to top the charts once more when Celta Vigo visit the Nou Camp this evening? Stick with us and you will see as we have live text commentary from 19:00 GMT.

It is only a matter of time surely?

Barcelona's little magician Lionel Messi could already be a regular on the old BBC One TV show Record Breakers.

The Catalan's record goal scorer. Tick. Most Ballon d'Ors. Tick. Record number goals scored in a calendar year. Tick. Most goals scored in a calendar year. Tick.

By 9pm tonight, the Argentine could be celebrating another memorable milestone.
