Plenty has been said already about Liverpool's remarkable Premier League campaign so far.
After reaching the dizzying heights of a Champions League final at the end of last season, the Reds have continued their ascent and are the current front-runners for this season's Premier League title.
The side's devastating front three of Mohamed Salah, Sadio Mane, and Roberto Firmino have all continued their tantalising form of last season. Meanwhile, Virgil van Dijk has proven himself as the perfect missing piece to the puzzle since arriving in January.
However, Jurgen Klopp's former club, Borussia Dortmund, are also enjoying a remarkably promising campaign as they sit atop the Bundesliga.
Both situations tell a similar story. Defending Premier League champions Manchester City have dropped to third place after two consecutive losses, meaning Liverpool are now six points ahead of Spurs in second.
Meanwhile, defending Bundesliga champions, Bayern Munich, also seem to be struggling - for their standards - as they sit six points behind Dortmund.
Having previously led Borussia Dortmund to a Bundesliga title, Klopp has now revealed who thinks is more likely to win their respective leagues this season.
"It's true that in recent weeks we have often sent congratulatory text messages back and forth [between Liverpool and Dortmund]," he told Bild.
"In England, you have to deal with Man City, Tottenham, or Arsenal. Dortmund only really have to fight Bayern - and that's the difference.
"We should all look at the calendar: the only thing that's over is the first half of the season. It's going to be tough for both teams."
However, it appears that Klopp hasn't escaped the threat of Bayern Munich this season. He too will have to find a way to topple the German champions as the two sides have been drawn against one another in the Champions League.
Speaking about the matchup, Klopp continued: "What happened to Bayern this season doesn't matter. We have to prepare ourselves for the best Bavaria.
"We've seen in the past two or three weeks before the winter break that they're strong again."
Does Klopp have a point? Do you think Dortmund are more likely to reach domestic success than Liverpool this season? Let us know in the comments.
