Bayern's Juan Bernat is shown yellow for a tug on the sleeve of Ricardo Quaresma as the Porto man scoops the ball over his shoulder and sets off in chase.

Bayern have not got a lot of firepower on the bench if they want to go more attacking.

In fact they have got two goalkeepers - Pepe Reina and Ivan Lucic are both riding the pine.

That doesn't look like tactical genius.

KoloKK: 10mins in, and Ricardo Quaresma is already on a hat trick! Against Bayern...

Rizpey: Am i seeing things? Im guessing ALOT of people will not be happy with bets. But on a serious note, Munich all over the place.

In the Championship Watford have taken an early lead against Nottingham Forest at the City Ground. Nigerian striker Odion Ighalo scoring a fourth minute header.

In League Two Danny Grainger has scored a free-kick after two minutes to put Carlisle in front against the league leaders Burton Albion.

Daniel Woodley: What is happening to Bayern Munich? Being taken apart by Porto! Didn't expect this!

Well, this is a right little pickle isn't it?

Pep Guardiola has the cogs whirling on the sideline, deep in thought about how to turn this scoreline and situation around.

Hmm, anyone see that coming?

Bayern Munich's defence have been hustled and harried and they have now coughed up another gift of a goal.

It is Dante this time who is caught in possession, allowing the ball to slip under his foot Gerrard-style.

Ricardo Quaresma is onto it in a flash, darting in on goal and slipping the ball past Manuel Neuer with the outside of his foot.

Peter Collins: Wait... WHAT? Bayern are losing?! That wasn't meant to happen!

Jackson Martinez was a touch-and-go for this one after picking up a minor injury, but he has been everywhere in the opening stages.

Very lively.

The referee got that call bang right.

It looked like Manuel Neuer had taken the ball cleanly as he hared off his line, but the replays showed that he went through Jackson Martinez to get it.

The Bayern goalkeeper looked pretty genuine in his disagreement though.

A rather shonky sidefoot to the bottom left from Ricardo Quaresma, but it doesn't matter because Manuel Neuer has flopped in the opposite direction.

Bayern have a little hole to dig themselves out of now.

What a start for Porto!

Jackson Martinez robs a dawdling Xabi Alonso on the edge of the box and is then floored by a sliding Manuel Neuer.

Penalty and a yellow card. And Bayern can consider themselves lucky.

We are up and running. The Estadio do Dragao is looking mighty fine.

Porto captain Ricardo Quaresma is no longer the sleek boyband wannabe by the way.

His latest look is a man on a 10-15 stretch in San Quentin - complete with tramlines and knuckle tattoos.

Right, let's get the cast-lists.

And despite Franck Ribery, Arjen Robben and Bastian Schweinsteiger all being out, it is still a tasty team that Bayern have out.

Porto XI: Fabiano, Danilo, Maicon, M. Indi, Alex Sandro Casemiro, Herrera, Torres; Quaresma, Jackson, Brahimi

Bayern Munich XI: Neuer, Alonso, Dante, Thiago, Lewandowski, Rafinha, Boateng, Bernat, Götze, Lahm, Mülle

Standing in the way of Bayern Munich tonight are Porto.

They have not bothered the last four of the Champions League since Guardiola's old sparring partner Jose Mourinho was steering the ship in 2004.

But the Portuguese side are unbeaten in the competition this year and did a lovely job on Basle in the last round, rolling over the Swiss 5-1 on aggregate.

Less than two years ago, they were contesting the Champions League final at Wembley.

But while Borussia Dortmund have slipped backwards under Jurgen Klopp, Bayern Munich have been turbocharged by the appointment of Pep Guardiola.

The Bavarians are 10 points clear at the top of the Bundesliga, lead Dortmund after the first leg of their German Cup semi-final and have their sights on a fifth straight Champions League semi-final.

"Pep doesn't just have a plan A, B or C, he has the whole alphabet from top to bottom," said Bayern chief executive Karl-Heinz Rummenigge.

Who must be mighty relieved that it has all worked out so well after giving coach Jupp Heynckes the heave-ho just before he won the treble in 2013.

The end of an era over at Borussia Dortmund...

...but at Bayern Munich it is business as usual.
