Champions League Results 2015: Updated Scores from Round-of-16 2nd-Leg Fixtures

Paris Saint-Germain sent a cynical, disappointing Chelsea out of the UEFA Champions League after a fiery, extra-time classic.

Before that, Bayern Munich and Porto were in ominous form as they advanced to the quarter-finals. They both hammered their opponents at home after disappointing showings in their first-leg matches.

Holders Real Madrid joined them in the last eight. But their indifferent form in La Liga appears to have bled into Europe's premier club competition. Los Blancos went through, but not without a few blushes after Schalke actually won at the Bernabeu.

Here are the full scores from all the round-of-16 second-leg fixtures:

Match	Scores	Aggregate Result
Porto vs. Basel	4-0	5-1
Real Madrid vs. Schalke 04	3-4	6-5
Bayern Munich vs. Shakhtar Donetsk	7-0	7-0
Chelsea vs. Paris Saint-Germain	2-2	3-3: PSG qualify on away goals

Recap

Huge controversy was tied to the evening at Stamford Bridge. It began when PSG striker Zlatan Ibrahimovic received a straight red card for a clumsy tackle on Chelsea midfielder Oscar.

Referee Bjorn Kuipers appeared intimidated when Chelsea players surrounded him in numbers. That might explain why he reached so quickly for the red in what appeared to be something of a knee-jerk reaction.

Squawka captured a closeup of the flashpoint challenge:

Oddly enough, PSG were by far the better side for large portions of the match after going down to 10 men. They passed the ball with more assurance, and their movement was clever and dangerous.

That combination helped create several glorious chances. The best fell to striker Edinson Cavani. But as he often does, the less-than-efficient Uruguayan spurned the moment.

Still, Chelsea continued to be static and lacked ideas:

Eventually, a series of bitty fouls and testy exchanges slowed the game down. Chelsea took full advantage once Gary Cahill sweetly struck a loose ball into the net, following a scramble from a set piece.

But Stamford Bridge old boy David Luiz crashed in an equaliser. Anyone who thought things would slow down in extra time soon had to guess again.

Luiz's fellow centre-back Thiago Silva bizarrely handled in the box. Eden Hazard, anonymous up to that point, stroked home the resulting penalty.

But the night had one more shock in store.

Silva went from scapegoat to hero after he met the second of successive corners with a bullet header to send the Ligue 1 giants through.

Chelsea's failure to make a man advantage count will be bitterly disappointing. But their shocking early exit owed as much to a poor performance and some cynical tactics to sway the officiating.

If Chelsea were static, Josep Guardiola's Bayern were anything but. The 2012/13 winners attacked Donetsk with pace and verve from everywhere on the pitch.

In a breathless display of adventurous football, Thomas Muller and company helped themselves to seven rapid-fire goals. The movement of players like attacking midfielder Mario Gotze was an object lesson in how to create space and open up a packed defence.

But perhaps it wasn't the goals that really symbolised Bayern's dominance. Opta Franz provided this detail that highlighted how far ahead Guardiola's men really were during this tie:

After a tame goalless draw in the first leg, Munich have reminded the rest of the field that they are still a force to be reckoned with.

The previous day's games saw a stuttering Los Blancos side stunned at home by a defiant Schalke, but a 4-3 win wasn't enough to see the Bundesliga side through.

It was, however, enough to prompt Madrid's free-scoring forward Cristiano Ronaldo to refuse to speak to the press for the rest of the season, according to Sky Sports.

There are deep problems currently plaguing the cup holders. Manager Carlo Ancelotti faces a tough task righting all of them before the next round.

One dark horse to watch out for at that stage is Porto. An exciting squad brimming with forward-thinking flair blew away Basel with a quartet of fine goals.

As he often is, electric winger Yacine Brahimi was the star. But rapidly improving midfielder Casemiro also impressed.

With so much quality in forward areas and a daunting home advantage, Porto could shock one of the competition's elite in the last eight.

Of course, one of the big shocks is Chelsea's exit before the quarter-final draw. But PSG certainly merited their memorable night.
