Thomas Muller's header definitely the best opening of the game so far. Bayern are dominating possession but Dortmund are looking solid. Apart from the awful marking at that corner of course.

Erik Durm's been a busy lad in these first 15 minutes or so. Already he's been up threatening on Bayern's left and now he covers Juan Bernat to concede a corner.

Xabi Alonso floats it in and Thomas Muller flashes wide with a free header. Of all people, surely you pick up Muller?

Shinji Kagawa. He wasn't great for Manchester United, granted. But he's been looking far more comfortable in the yellow of Dortmund since. The Japanese is found by Marco Reus and sprays a pass out wide looking for Erik Durm, but there's too much on it.

The first interchange of note from Dortmund though. Slick in the midfield as Reus picked the ball up and turned on Bayern's goal.

Thomas Muller floats a ball in looking for Robert Lewandowski but it's poor and Australian Mitchell Langerak can gather.

At the other end a Sven Bender pass is over-hit. This one is yet to get going in earnest.

Neuer played in Schalke's 5-0 victory over Duisburg in the 2011 German Cup final, before moving to Bayern later that year. The Bavarian club have feature in each of the last three finals, winning twice.

He was Germany's 'sweeper-keeper' at the World Cup but will he have much to do tonight?

The early signs are ominous for Jurgen Klopp's side as Bayern stroke the ball around very comfortably. Like a team who've just won the league.

Marco Reus. Boy do Dortmund need a big performance from him tonight. This could be a game of few chances for the away side.

Bayern get us going and Thomas Muller finds space on the left immediately. His cut-back is cut out.

Here we go then. Pep emerges from the tunnel to embrace a still-beaming Klopp and the two banks of players shake hands.

Dortmund huddle, while Bayern's players high-five.

Before we get under way a word to the wise.

Barcelona are also in action tonight, at home to Getafe. Luis Enrique's side are already 4-0 up after just over half an hour played.

The Bayern fans are pumped, the stands are packed and we are almost under way.

Dortmund were bottom of the table in January but have since crawled their way back to obscurity and eighth. Qualification for the Europa League remains a possibility, but far more glorious would be silverware and a ticker tape parade on Klopp's last day on 30 May.

Their opponents tonight beat them in the final of last year's competition, but Dortmund routed Bayern 5-2 to win the cup three years ago.

"We have to know that we have been an uncomfortable opponent for Bayern," said Klopp. "I have the feeling that we are not without a chance against them.

"Bayern does not gift anything away and that is why we must be present with all our senses from the very beginning. But I can't reach this aim with my words. We have done many things so that we can compete well, but we must bring the performance to the pitch. This game is everything."

Already your predictions as to where Jurgen Klopp might be managing next season are flying in.

Pep is certainly not taking Klopp's challenge too lightly. Bayern beat Dortmund 2-0 in extra-time to win last year's German Cup but the former Barcelona boss isn't counting his chickens.

"He is a super guy," Guardiola said of Klopp. "I think our relationship has been very good right from the beginning. We have the last game against each other. He wants to win and I want to win. This game is completely different situation to last season. It's very close."

The form book says Bayern should stroll this, with the Bavarians having already done the double over Dortmund on their way to being crowned German champions for a record 25th time this season.

With four league games to spare Pep Guardiola's side can now switch their focus to matching the success of 2013, when Jupp Heynckes led the club to the treble of Bundesliga, German Cup and European Cup.

Bayern have one job out of the way and face Barcelona in the Champions League semi-finals on Wednesday. But tonight they are up against a side looking to silver line a season to forget. Dortmund could be dangerous.

So Klopp is off at the end of the season after seven years in which he won two Bundesliga titles, the German Cup in 2012 and reached the 2013 Champions League final, losing 2-1 to Bayern at Wembley.

This ain't the time for no goodbyes though. The floppy-haired one is focussed on setting the stage for what would be a grand finale at the Olympic Stadium in Berlin on 30 May. So much so that he gave Bayern's offer of a floral presentation in respect of his achievements at Dortmund before tonight's game very short shrift indeed.

"It's a nice gesture," he said. "But we're armed for battle and we don't want to be softened by being given flowers. I don't sense any end-of-an-era feeling."

But what about Pep Guardiola you say?

Well Franz did also stress how much he likes the Spaniard, who is expected to extend his role as Bayern manager beyond the end of next season.

"I can't imagine Guardiola would leave in 2016," the former Bayern defender said. "He likes Munich. He has had success with the team and he knows that he can succeed in the future. He has everything he wants."

Still, Pep to City, Klopp to Bayern? Would that mean Manuel Pellegrini goes to West Ham?

Are you ready for Jurgen Klopp's last 'Klassiker'? Or at least, his last as Dortmund manager?

Since the 47-year-old announced he was stepping down at the end of the season speculation on his next destination has been lurching all over the place.

First he was taking a break, then it was Manchester City, next West Ham and now? Who knows?

But just when we thought the options were narrowing Franz Beckenbauer came out with the intriguing prospect of Klopp taking over at Bayern Munich… , external
