There were no seeded teams nor country protection, meaning Germany's two representatives - and last season's finalists - could theoretically have been pitted together. As it transpired, they weren't - but the draw was always going to be tough whoever came out of the hat...
The complete quarter final draw is as follows:
FC Barcelona - Atletico de Madrid
Real Madrid CF - Borussia Dortmund
Paris Saint-Germain - FC Chelsea
Manchester United FC - FC Bayern München
Contra el Manchester United en cuartos. Gran eliminatoria!!! #MiaSanMia— Thiago Alcantara (@Thi_Alcantara91) March 21, 2014
"We knew there would only be top games in the quarter-finals and there were no opponents I would have gladly said, 'let's get them'."
"It's a fantastic draw! It's a dream stadium with a fantastic atmosphere. There have been plenty of great games between us down the years and I'm really looking forward to it."
Dortmund captain "Real's a fantastic draw. They're going to have revenge on their minds from last year and they're a bit stronger now than they were then and they're going to be fully focused for this tie. It could be a small advantage playing in Madrid first. However, there are no easy opponents in the quarter-finals any more."

"It's a good draw," said Jürgen Klopp (pictured). "When you make it into the last eight once again, then you've got to expect a repeat draw now and again - and that's what's happened to us. They're going to be two games with a cool atmosphere and we're really looking forward to the challenge. We'll try to make the most of the small chance we've got. It could be an advantage that we're playing in Madrid first. We certainly won't be raising the white flag."
The first reactions are filtering through... Bayern's sporting director Matthias Sammer has warned against reading too much into United's current Premier League position. "They're deadly on their day, so let's just hope they don't have two good days," he said. Defender (pictured) is preparing for a test of his mettle against Dutch destroyer Robin van Persie. "He's a world-class player, but we don't need to be afraid," said the Brazilian.
No prizes for guessing who Borussia Dortmund will have to pay particular attention to when they renew acquaintances with Real Madrid CF, this time at the quarter-final stage after prevailing 4-3 in the semi-finals last year. Cristiano Ronaldo (pictured, r.) is the competition's top scorer this campaign with 13 goals.

So there we have it, a repeat of the 1999 UEFA Champions League final with FC Bayern up against familiar foes in Manchester United FC. Wayne Rooney (pictured, r.) will be the man Bayern will be looking to keep out of danger when the sides meet, first at Old Trafford and then a week later at the Allianz Arena.

FC Bayern have familiar foes Manchester United to overcome on their way to a second straight final. The first leg will take place at Old Trafford.
It's a repeat of last season's semi-final for Borussia Dortmund, who head to the Estadio Santiago Bernabeu for the first leg against Real Madrid CF.
Paris Saint-Germain to host Chelsea FC.
FC Barcelona first out of the pot, and they have a home tie against Club Atletico de Madrid, an all-Spanish affair to start with.
The final ambassador, Luis Figo, has taken to the stage. We are now moments away from discovering what mouthwatering ties to expect next month.
Can Bayern become the first to win the trophy twice in a row? Luis Figo thinks it will be hard: "The quality of the teams is different each year. Each year, the teams try to become stronger and stronger. It depends [...] if you have a bad day or not, you can be in that dream final in Lisbon."
Bayern and Dortmund will be hoping to be kept apart in the draw, but a repeat of last May's final is a prospect. Check out what happened the last time the Bundesliga giants met, on Matchday 13, courtesy of the Bundesliga's official YouTube channel.
For the second year running, FC Bayern were up against Arsenal FC in the last 16 of the Champions League and once again, the Bavarians prevailed. It was more clearcut that a year ago with Bayern once again winning the away leg, but they did not suffer so much on home turf as a draw completed a comprehensive victory.
Dortmund thought their passage to the last eight was going to be a breeze after they clinched a 4-2 win away to FC Zenit in the first leg. However, it proved to be a more challenging second leg at the Signal Iduna Park, although a 2-1 defeat was not enough in the end to harm Jürgen Klopp's men.
If you missed any of the last-16 ties involving Bundesliga sides, we have a gallery of all the best moments, including Bayern's and Dortmund's victories, and Schalke's and Bayer Leverkusen's eliminations.
