They have blown away teams so far this season with their high pressing and attacking game.
However, the three behind them have also had their moments this season. Chelsea thrashed Everton 5-0 on Saturday,a great considering how good a team Everton are anyway. Manchester City started the season like a train and were beating teams for fun while Arsenal are looking more like a title winning side this season.
So what is the best combined team of these four clubs so far this season? We'll go with a 4-2-3-1 formation as it is the most common.
Goalkeeper - Petr Cech
Arguably, the two best goalkeepers in the in Hugo Lloris and David de Gea fall just short of contention of this list, but there is still some talent in the ranks.
It has been a difficult start to Premier League life for both Claudio Bravo and Loris Karius at Manchester City and Liverpool respectively. Bravo made a high profile error in his debut at Old Trafford that allowed Ibrahimovic to score in the derby while Karius has looked unsteady with his command of the box and decision making.
The other two in Cech and Thibaut Courtois are now Premier League stalwarts, with Courtois especially improving on his poor displays last season. However, Cech just edges this one.
Right-back - Hector Bellerin
The young Spaniard has been in sensational form this season and looks to have brought a more mature defensive style to his play to couple his explosive attacking threat.
Manchester City's two right-backs in Pablo Zabaleta and Bacary Sagna have been relatively poor this season and cannot be considered. Victor Moses has been a pleasant surprise for Chelsea so far this season, but has not played in a more conventional fullback role while Nathaniel Clyne has been good but not quite as good as the Arsenal man.
Centre-backs - Shkodran Mustafi and Joel Matip
The two recruits with obvious links to German football have both been outstanding so far this season. Mustafi finally looked looks like the proper defender Arsenal have required to partner the more ball playing defender Laurant Koscielny.
While, Cameroon international Matip could be one of the bargains of the season after joining the Reds on a free transfer. It took him a while to get it and started, but he's looking like a mainstay in Klopp's ever improving.
There aren't too many others that can be mentioned in all fairness, though John Stones has had a decent start to his City career and certainly doesn't warrant the criticism he is receiving.
Left-back - James Milner
It speaks volumes for the 30-year-old's ability to slot in anywhere on the pitch and perform well that he gets in this team despite having never played at left back before this pre season. With Alberto Moreno proving a liability and Jon Flanagan being sent to Burnley to regain his fitness, the position needed a steady mind and Milner fits the bill.
Elsewhere, Marcos Alonso is now getting into the Chelsea team after his surprising move on deadline day, but there isn't too much to shout about in this position.
Central midfield - Jordan Henderson and Ilkay Gundogan
The much maligned Henderson has been one of Liverpool's star men so far this season. Klopp has found a new role for the 26-year-old and his game is about doing the simple tasks effectively, like keeping the ball ticking and winning it back in midfield. His passing was superb against Watford and his presence allows Liverpool's attackers to flourish.
While Ilkay Gundogan, like Matip at Liverpool, is proving to be a shrewd signing for Pep Guardiola's side. He's a deep lying playmaker so isn't as gung ho as his team mates Kevin De Bruyne and David Silva, but he's managing to chip in with a few goals for his side.
N'Golo Kante can feel hard done by to miss out, and he has slotted into the Chelsea side seamlessly and is doing exactly the same job he did at Leicester, but Gundogan just shades it.
Right-wing - Eden Hazard
The Belgian winger was comfortably the best player in the Premier League two years ago in Chelsea's last title campaign. Last season though, he was abysmal by his very high standards and only grabbed his first goal in April.
However, this year he getting near to his best form once again and is showing all the dribbling ability and flair that makes him such a matchwinner when on song.
Number 10 - Mesut Ozil
It's been a long time coming, but Mesut Ozil is finally looking like a consistent £42 million player that Arsene Wenger bought three years ago. He has always shown his ability in patches of form, but otherwise has tended to go missing when it mattered.
This season, he not just the usual assist magician but is starting to make more forward runs and in turn scoring more goals for the club. The pace of Alexis Sanchez up front is opening up the space for the German to exploit and he is looking more like Rolls Royce footballer every week.
Left-wing - Phillippe Coutinho
Although not a natural wide player, the Brazillian is more than adept at coming in from the wing into pockets of space to shoot or thread a neat pass through to the forwards. He has been Liverpool's main man this season and despite how impressive all of Liverpool's attacking players are, it would stick out if he was missing.
His goal against Watford yesterday exemplified how brilliant his technique is. A sharp touch to take it inside followed by a low drilled shot with barely any back lift. He has been superb so far this season.
Striker - Diego Costa
A best XI in the Premier League at any time without Sergio Aguero seems ridiculous, because the Argentinian always scores goals and is a nuisance for defenders constantly.
However, Costa is in the form of his life and returning to the absolute best he displayed when he first came to the club from Atletico Madrid. He is strong, robust but also a very good footballer and his long range strike against Southampton last week proved that once again.
He is also toning down his aggression which shows just much he is currently enjoying his football under Antonio Conte.
