Jurgen Klopp must be wary of Man City because they always play consistently before the season ends and we can see how they were able to catch Arsenal in points in the previous season even though the distance was not close. This must be taken seriously because if Liverpool is careless, Man City will top the standings and Liverpool will compete much more fiercely.
I think everyone knows how good City can be in title run-ins, we have seen it happen time and time again and Jurgen Klopp knows firsthand what it is like, because City have pipped him to the title on a number of occasions, but this season looks somewhat different; City are not playing in that menacing way we have come to know them for. City's last two games against Brentford and Bournemouth respectively were tougher than anybody thought they were going to be, whilst the other title contenders (Liverpool and Arsenal), have been flying of late and scoring goals for fun, Pep knows they must improve, if not either Liverpool or Arsenal will take the title from them.
I get your point about City's recent form. It's not our usual City, right? My opinion is that points matter more than showy wins. Arsenal's goal difference is great, but those 3 points each match matter most. I think City is just in a slump, but Pep can turn things around when it matters. He manages the team's season well. Let's not write City off yet. With Guardiola strategizing for the long term, they have the depth and strategy to come back strong
