Liverpool boss Jurgen Klopp speaking to MOTD: "[It feels] As low as possible. Massive, massive blow because I have no idea how we can lose this game to be honest. Not that we played exceptionally well, not that I expect that but it would have been nice.
"With all the changes we had to make and with the intense week behind us it was clear we had to make a fight of it. The boys did that. The chances they had were pretty much counter attacks where we gave the ball too easily away. We were dangerous and a real threat and the set pieces were 100% chances pretty much. That we didn’t finish one of these off is the main blow if you want because we cannot put them in better, you cannot move better and if you have one player completely free in the box that is the perfect set piece.
"The goal we conceded was giving the ball away in a situation which should not happen, then the set piece was sloppy and they finished it off."
Nottingham Forest midfielder Ryan Yates, speaking to BBC Sport: "We needed that, a few weeks ago it was tough, five consecutive defeats. We had to go back to basics and get that team shape and slowly week by week we're getting points.
"We knew what the fixture meant to the fans and from minute one we wanted to put them on edge of their seats with a high energy game.
"It's been weeks of nearly being there and at the wrong end of a few things of our own making. We've put in a great performance today, it's three points but it's not enough. We need to be out of the bottom three."
On his own high-energy and industrious performance: "I need to be a nuisance and show that quality on the ball. I thought I'd scored, could not believe Alisson saved that.
"The strikers said he comes out quick so wait an extra second and lift it. I did that and he still saved it!"
On what the win must do for Forest: "It's got to propel our season. If we can beat Liverpool we can beat anyone. It is not going to be smooth sailing but it has got to give lads confidence."
