Klopp said: “You could see it was an intense game for the three up front.
“It was hard for the starting front three, and I was really happy we could do that (replace them).
“I was not in doubt about the quality of the boys (who came on). The game was pretty wild and we defended all together.
“We were defending 4-5-1 and both wingers needed to be really involved in the defending. The moment you win the ball, then there are big spaces for counter-attacks, and we thought it made sense to bring on fresh legs.
“All three who came on are in really good shape, they all really helped a lot.
“Shaq won deflections, which was pretty special! Taki in both directions was incredible between the lines and Diogo is a machine, he can do a lot of punishing of opponents in one-on-one situations.
“We didn't finish them off unfortunately."
