After beating Manchester City before the international break, Liverpool extended their unbeaten home record to 47 Premier League matches.
Much of what followed in the international break, with the fight between Raheem Sterling and Joe Gomez, seems to have stemmed directly from their Anfield clash.
Each and every one of Jurgen Klopp's Reds seems to defend themselves. Your character and mindset for winning are now rooted in the core of every team member.
It seems to be a minimum requirement to play for the mentality giants.
Where this mentality came from was a discussion in Blood Red's latest Poetry in Motion podcast, with Liverpool clearly falling under the skin of Pep Guardiola's Man City last Sunday.

It was a point of discussion raised by Neil Fitzmaurice, who, despite all the exciting offensive play, was delighted to see a new side of the Reds: “One interesting thing I noticed last season with Liverpool is that they can mix.
“There were some instances in the game (Man City) where Trent threw his hand at Raheem Sterling, pushed him (for publicity), Robertson and Walker as well.
"It reminded me of Messi, Robertson pushing Messi, they no longer suffer from fools. They are not surprised.
"I love it because I really feel that these Liverpool players know their value, not in an arrogant way, but don't come here and think you're better than us, because it's not and it goes through the team . ”
Liverpool ECHO correspondent Paul Gorst gave his explanation of where he came from: “I think there was a big improvement that few people would get in immediately.
"I will always remember the Champions League final against Real Madrid, Sadio Mane was marked by a foul against Sergio Ramos where he overreacted, Mane helped him with a handshake and a big smile on his face and he is getting a card yellow.
"You're losing the game, you think Liverpool need to do this kind of thing (the dark arts), little vein here and there and they seem to have achieved it over the last year."
Fitzmaurice, however, recalled a more recent European tour, which led to Anfield's biggest night: “I was at Nou Camp when we won 3-0 and I think there was a lot of bullying, a lot of bullying for the referee. .
"There was a story about Messi calling Milner a donkey in Spanish and Milner got it.
“I think there was a turning point, because when they arrived at Anfield, with Fabinho going through Messi, there was a turning point that trampoline the whole 4-0 defeat, where Liverpool realized we're better than that, we don't know deserve to be treated like that. "
Caoimhe O'Neill, also part of the panel, believes the two games already mentioned are linked to give Liverpool additional mental resilience:
“It stems from the Champions League final (against Real Madrid). Sergio Ramos is the master of the dark arts, isn't he? The good thing with Liverpool and the Barcelona game was that we had a second bite of apple.
"Klopp would have come in and said, we are 3-0 down, but in between those games, we look into that and think what we could have done in that final that we didn't do, that we can do now to turn the game around."
Adding: “From the beginning, we put on them. Suarez making these moves, we love when he was our player, but it's so hard to watch when they're playing against you.
"I wouldn't say Liverpool are rolling in agony and things like that were subtler back thrusts, we saw that against Man City.
"I think it's the way of champions, it's a subtle art, but I think once you master it, I think one of the missing ingredients wasn't for Liverpool, and now they're interested."
While Robertson and Alexander-Arnold were the two obvious examples of Liverpool's winning mentality at Anfield against City, Gorst says he runs from the top of the locker room.
“Players like Milner and Henderson are also important to this. I remember when Liverpool played at PSG last season, Milner fighting Neymar at the beginning, as if to say, "You're in Anfield now and this is us."
"For years Liverpool have been, perhaps, very nice and a team of choir boys, but now they seem to have an edge over them and I am in favor of that."
