Liverpool were able to overcome early struggles to beat Burnley 3-1 this afternoon - and they did it in front of a record league attendance at Anfield.
Some 59,896 supporters were present as the Anfield Road development surpassed its latest milestone, opening up its hospitality to fans.
It breaks the previous record for a league game held at Anfield of 58,757, a record that had stood since December 1949.
On the close-to-filled Anfield Road Stand, Klopp said: "Outstanding. Oh my God! Before I really heard it, I saw it already. It looks exceptional. Absolutely exceptional.
"This stadium grew and grew, it was always wonderful but now it's really outrageously wonderful. Really top. Really top. Really loud in the right moments."
With more eyes on an Anfield league fixture than ever before, it wasn't the perfect start for Liverpool, who endured a sluggish start against the Clarets.
However, despite their poor display, they were the side that took the lead, with Diogo Jota pouncing on an error by James Trafford to head in to an open net.
The Reds were unable to hold onto their lead until the break, though, with Dara O'Shea heading a fantastic header into the top-right corner on the stroke of half-time to equaliser.
And after David Fofana threatened to level the score down the other end, it was Darwin Nunez who gave the Reds breathing space with 11 minutes to play, brilliantly directing his header past Trafford with Elliott notching another assist.
However, work on the Anfield Road Stand is still to be done, with the club not yet able to reach that capacity crowd.
The stand still requires finishing touches to the back rows of the upper tier and the away end before the project can be declared complete, allowing the elusive figure of 61,000 fans to clamour inside Anfield.
