Liverpool FC made Pep Guardiola's warning clear right before Manchester City's match at Anfield

Digital Desk: Question and curosity always rises when the finest football team in the world visits the most challenging stadium in England!

The Premier League match between Pep Guardiola's in-form Manchester City team and Jurgen Klopp's Liverpool will reveal that on Sunday. Erling Haaland was scoring goals for joy, and City, who were second in the table and unbeaten, were the obvious favourites on Monday. 

With three more costly injuries and a recent loss to Arsenal, Liverpool had fallen to 10th place in the standings, and Klopp was using his press conferences to criticise the calibre of the questions asked of him rather than respond to them.

Following that, both teams travelled for 180 minutes in the Champions League, which brought their respective recent forms closer together before of their match on Sunday. 

Man City rested some key players in Copenhagen, including Haaland, but were held to a frustrating draw. Sergio Gomez's red card, which forced his teammates to play against 11 men for an hour, didn't help either. It was a small setback for City before what their manager called the "toughest test in English football" and any intentions to rotate players like Joao Cancelo, Kevin De Bruyne, and Rodri using the five substitutes allowed.

At least, they were up until the second half at Ibrox, when Rangers gave in and Klopp's team devastatingly seized the opportunity. Mo Salah's debut was the last thing Rangers wanted to see after falling behind 3-1, and within 13 minutes of his entry, it was six thanks to Salah's stunning six-minute hat-trick, which exhibited all of his greatest and most dangerous traits. 

In his post-game news conference, Klopp was able to shed his grumpy-dad demeanour and claim that the atmosphere in the locker room had "totally transformed." Add two more goals for the surprisingly prolific Roberto Firmino, a useful score for Darwin Nunez, and a beloved Harvey Elliott cherry on top.

That's nice, but this will be a different game, and we all know who we're welcoming on Sunday, he remarked. But it's better to feel confident going into the game as we do tonight! We'll see. I'm always ready for a change for the better, but we'll have to wait and see. 

"We don't need to make a great deal out of the fact that on Sunday, the best football team in the world will visit Anfield. We'll investigate our options. Not at all, but it's not like we show up shouting, "We are waiting!"

While Klopp refrained from proclaiming Liverpool back in the battle for the title or even as favourites against City, he will be much more confident of achieving a victory now that his forwards are playing with some impetus for the first time this season. Salah's cameo in particular had echoes of some of his best and most significant former performances against City. 

Guardiola won't be surprised by any of it, even though his claim that playing at Anfield would be his team's "toughest test" may have raised some eyebrows considering the teams' divergent recent performances.

Nonetheless, he's always understood that, regardless of injury or form, Liverpool have enough world-class players to overcome his team, as they hinted at Ibrox. He'll also be well aware of City's one win at Anfield since 2003. 

City will still be favourites for Sunday's clash, but the midweek results will have increased their odds against a Liverpool side with some wind in their sails and a point to prove.
