This post from Reddit sums up some of my feelings pretty well, particularly after watching the footage above:
"fudge every last person who says the players don't care or didn't try.
This video shows the empathy that professionals have for each other. Think rival fans are often too mean-spirited to each other and to the players... I'm certainly guilty of it. Don't think we understand what is truly put into it, but you see the players always backing each other.
Klopp knows exactly how they all feel because he's felt it himself...he's definitely one of the good ones. It was good to see him come over to Son."
