It has been a tough start to the season for the Reds.
Their hopes of challenging for the title may be over as they are 14 points behind the leaders.
Three successive wins has left them on the verge of progressing to the knockout stages for the sixth season in a row, after they were thrashed by Napoli in the first game of the season.
They went into the half-time break level at one apiece against Rangers, but went on to win 7-1.
Jonathan Woodgate was a former England defender.
"You can see what the team can do in the second half," said the former player.
You will get a lot of confidence from that performance.
It looks like they have regained their spark.
They will play Manchester City on Sunday before games against West Ham andNottingham Forest.
They will have a chance to make it to the knockout rounds.
The game will be different, but he hopes the win at Ibrox will help.
The win definitely changed the mood.
It's been a long time since we've had a beer after a game.
We can be a great team when we are on it. The second half is a result of the first half because we built on the good things from the first half.
We all know who we're welcoming on Sunday, so that will be a different game. It's good to be going into that game with a sense of satisfaction.
The result was good, and they showed the quality we need for the rest of the season according to centre half van Dijk.
The Dutch defender said that it was not a bad thing to win 7-1 on the road.
We took it a game at a time and everyone expected us to win. We will be ready for the big one on Sunday, even though they are in great shape.
After four league games without a goal or assist, the Egyptian came off the bench and scored a hat trick in six minutes.
Firmino has five goals in his last three games.
The latter's performance was "magnificent" according to Woodgate.
Woodgate said thatFirmino had a good start to the season.
The positions he was getting himself into and taking up, as well as his awareness when he gets the ball, is just fantastic.
Michael Owen said Firmino was the star player even though he scored three.
Owen said Firmino is top quality. He scored two important goals and the rest is gravy.
He is on fire. He was able to get into the right areas by reading his position.
I hope things work out for him. We will work together on it.
Owen said a lot of people had Firmino fifth in the pecking order and now ahead of their biggest game, you can't believe he isn't playing. He can't be left out by the coach.
Despite the one-sided nature of the final result, the first half was even and if Rangers had shown a bit more quality and composure in the final third, it could have been worse for the Reds.
Owen told them to get back to being ruthless.
When they play to their strengths, they are a good team, but I still see chinks and I am sure Man City will be looking at that.
They will be looking forward to the weekend now that they've scored.
"Manchester City will watch that game and see one or two things they will like", said Ally.
Rio Ferdinand said that people were happy with the mini decline. The opposition fans are not as far away as people think.
Individual moments where players lack confidence can lead to being back on top of their game again. It makes you feel confident.
If things don't go their way, Firmino and Salah will be bouncing with confidence.
"These things have to change for their season to change", said the manager.
