We took a look at how fans reacted to the game on social media.
Liverpool fans had a lot to be pleased with and it definitely makes their opening Premier League game of the season against Arsenal an interesting affair.
The Reds made a bit of history in putting four past Barca.
If you missed all the goals here they are.
Maybe a slight exaggeration.
A little over the top perhaps?
Another impressive stat! Wembley was packed as yesterday as fans turned out en-masse to watch two of world footballs biggest club battle it out.
If this is how fans were reacting when the third goal in we can only imagine the scenes when they put in the fourth.
Pretty much sums up Liverpool fans mood.
When John Barnes starts rapping on the tube you know it was a good day.
