Is there anyone who can stop Liverpool this season?

Jose Mourinho parking the bus looked to be one of the strongest answers to that question, but even his plucky Tottenham Hotspur side were no match for the omnipotent Liverpool juggernaut.

Roberto Firmino's winner in north London meant they had won 20 of their opening 21 league matches, which has never happened in any of Europe's top five divisions.

Add the Champions League title, FIFA Club World Cup, UEFA Super Cup and a 14-point in England, then you'll see exactly why Jurgen Klopp's men have such a smile on their faces.

But of all the records to be flying in Liverpool's direction, perhaps the most impressive one has emerged this week and it comes courtesy of the football statisticians at clubelo.com.

Greatest teams in history

They used a complicated Elo equation (see explanation here) that allows them to rank teams based on a number of factors and they've even done it for some of the greatest sides in history.

In fact, when you check out their scores for football's best ever teams, the current Liverpool side finds itself in fourth place with a differential of 2,074. Remarkable.

In other words, Klopp's team are statistically certified as one of the greatest ever seen and we've decided to breakdown the top 20 below so you can see who they're rubbing shoulders with.

20. Juventus (1995) - 1,966

Roberto Baggio captaining the Old Lady to glory in Serie A and the Coppa Italia, as well as reaching the UEFA Cup final, sounds like a suitably dramatic way to open up the top 20.

19. Valencia (2004) - 1,968

Claudio Ranieri might not make the cut for his Leicester team, but he does reach the list for taking the keys from Rafa Benitez after he led Valencia to UEFA Cup and La Liga glory earlier in the year.

18. Real Madrid (2001) - 1,969

Los Blancos hadn't quite relinquished their European title at this stage and they were on the path to something special with both Luis Figo and Vicente Del Bosque at the Bernabeu.

17. Borussia Dortmund (2013) - 1,971

That's right, Klopp makes two appearances on this list. Dortmund were desperately unlucky not to be crowned European champions with a side featuring Robert Lewandowski and Mats Hummels.

16. Hamburg (1980) - 1,972

Champions League final and Bundesliga title race defeats clearly did little to hamper a Hamburg team that featured double Ballon d'Or winner Kevin Keegan in their midfield.

15. FC Porto (2011) - 1,973

This is one inclusion we're iffy about. Andre Villas-Boas won every trophy under the sun with Porto in 2011 and apparently Branko Zebec's continuation of that glory is enough for a place in history.

14. Liverpool (2008) - 1,987

Ah, what could have been. It's interesting that Benitez's near-miss team, which lost just two Premier League games in 2008-09, gets the nod over more successful Reds variants in the 1980s.

13. Juventus (2018) - 2,000

This might not have been a year in which Massimiliano Allegri reached a Champions League final, but you know the statistics will shine brightly when you lose just one Serie A match all year.

12. Barcelona (1960) - 2,006

Real might have been crowned European champions, yet the Blaugrana were top dogs in La Liga - as well as the Fairs Cup - with the legendary Laszlo Kubala smashing in the goals.

11. Atletico Madrid (2016) - 2,024

Sure, this might not be the Atletico team that won the La Liga title in 2016, but they still make the cut for reaching a Champions League final and boasting one of the greatest defences ever fielded.

10. Manchester United (2008) - 2,026

Winning your second consecutive Premier League crown and a Champions League trophy with the likes of Cristiano Ronaldo and Wayne Rooney on top form is certainly worthy of greatness.

9. Chelsea (2008) - 2,026

Being managed by Avram Grant and Luiz Felipe Scolari might not be that glamorous, but this was a Chelsea side that reached the Champions League final and lost just two league games all year.

8. MTK (1955) - 2,037

The footballing world revolved around Hungary during the 1950s and MTK get the nod over their Budapest rivals Honved, who boasted Ferenc Puskas and Sandor Kocsis on their roster.

7. Manchester City (2019) - 2,047

Liverpool aren't the only 2019 team to make the list and Pep Guardiola's first entry of three reached a peak statistical rating in September, before they lost their stranglehold on the Premier League title.

6. AC Milan (1993) - 2,052

Fabio Capello in the dugout, Franco Baresi and Paolo Maldini at the back, Frank Rijkaard and Ruud Gullit in midfield, Ballon d'Or winners Marco van Basten and Jean-Pierre Papin up front. Nuff said.

5. Real Madrid (1961) - 2,069

This peak rating came when Real were the reigning European champions six time over and boasted one of the greatest striking dups ever witnessed: Puskas and Alfredo Di Stefano.

4. Liverpool (2020) - 2,074

Well wouldn't you look at this. It turns out making the best start to a league season in modern European football makes you pretty good at football, not to mention being kings of the continent.

3. Real Madrid (2014) - 2,096

Carlo Ancelotti commanded one of the freest-scoring Champions League winners in history in 2014 and it's no wonder they make the cut with a prime Ronaldo bagging 50+ goals a season.

2. Bayern Munich (2014) - 2,104

We're talking about a club side that won the treble in 2013 and then appointed Guardiola as their manager, steamrolling everything in front of them until they failed to defend their European crown.

1. Barcelona (2012) - 2,107

What. A. Team. Perhaps the only surprise is that Guardiola's magnum opus made the list in 2012 and not when they absolutely dominated United to Champions League glory the year before.

Nevertheless, their midfield trio of Sergio Busquets, Xavi and Andres Iniesta is the stuff of legend, while Lionel Messi - who notched 91(!?) goals that year - played up top as the certified GOAT.

GIVEMESPORT's Kobe Tong says

Call me crazy, but I have absolutely no problem with Liverpool finding themselves in fourth.

For starters, my hands are tied when it comes to creating a stronger objective system and the fact various eras of the sport are represented show everyone has been given a fair crack of the whip.

Plus, it's important to remember that we're talking about a football team's peak here, it's not a question of the fact Klopp's men have only been doing it for 18 months. That's irrelevant.

The point is that they're making the Premier League their playground right now, showing the equation that not only are they world-class, but they're absolutely capable of sustaining it. 

They're the European and world champion sand barring a collapse that would go down in sporting history, they'll also have that evasive Premier League trophy to show for their brilliance.

So, sorry to all those fans who've been laughing at Liverpool for the past two decades, but if you don't think they're producing a season for the history books, then you're simply in denial.
