Well, there isn't much more I can add that hasn't already been said about Chelsea's performance last night...but I'm going to anyway.
Going in to the game, Barcelona were heavy favourites being priced at 1/5 at some bookmakers, and that's even with Chelsea having a one goal advantage from the first leg at Stamford Bridge. That's how good Barcelona are at the Nou Camp; it seems to make the best team in the world even better.
So when Sergio Busquets cancelled out Chelsea's aggregate lead in the first half, it looked as if Chelsea had a real battle on their hands to make the final.
Somehow it got infinitely worse within five minutes.
In a moment of madness, John Terry decided to randomly knee Sanchez in the back, probably out of frustration. Even though in all honesty it was a weak red card, you are always running the risk of being sent off if you're involved in an off-the-ball incident.
And he was, and Chelsea were down to 10 men, and looking vulnerable in defence.
Barcelona then capitalised on this vulnerability and doubled their advantage, striking despair into Chelsea hearts everywhere.
2-0 down at the Nou Camp is bad enough, but with 10 men, Chelsea must have thought they were in for a long night.
But instead of rolling over, Chelsea began what turned out to be one of the most incredible displays ever seen in the Champions League.
Starting with Ramires' beautiful chip just before half-time to half the deficit, Chelsea's second-half performance was almost superhuman, keeping Barcelona from scoring for over 50 minutes.
And the gigantic cherry on the top was of course, Fernando Torres' blockbuster goal in stoppage time to guarantee the Blues' place in the final.
Here are some of the other greatest upsets in world football history.
