The Dutchman produced an excellent all-round display which included the fourth goal, as he continues a promising start since arriving from Bayern Munich.
It was after a question on Gravenberch, during his post-match press conference, that Klopp made sure to give Endo his flowers, too.
“I liked a lot of individual performances, but I would like to mention Wataru Endo,” he told reporters.
“I’m not sure people think that’s spectacular or whatever, but the forward passes he played tonight were absolutely incredible.
“And how often he broke lines with one touch, that was absolutely insane.
“Then he scores a wonderful goal, which helps each player, even a more experienced player. So that’s really cool.
“He would have got a similar hug [to Gravenberch] if I would have brought him off, but he had to play through.”
Endo is certainly deserving of praise for his latest performance, particularly in the context of a stop-start season so far since joining from Stuttgart.
A defensive midfielder by trade, Endo now has a goal and assist to his name in nine appearances for Liverpool – and against Toulouse made the joint-most passes into the final third per FotMob (eight).
