When Liverpool announced the arrival of Jurgen Klopp as their new manager in October, it sent fans' pulses racing and their minds dreaming - but even the most optimistic Reds supporter couldn't have predicted the new man would make such a quick impact.
When a new manager is appointed, it is only natural for players to give a bit more and improve their performances, if only for a few games; they want to impress the new man in charge and prove their worth.
However, what we are seeing with the German's Liverpool team is a bit different; a bit special.
It was a major coup when the Anfield side hired Klopp and although it is still very early days in his managerial career on Merseyside, he is starting to show why he was regarded a world-class boss prior to his arrival.
The most obvious change is the pressing and work rate of the team. In Klopp's first game in charge, his side were the first team to outrun Spurs this season.
It's not just mindless pressing, though - his team aim to quickly win back possession when lost, with their crushing 4-1 victory of Manchester City on Saturday epitomising the 'gegenpressing' style of play that Klopp has installed.
And it's clearly working, yet something he has also changed in the players is belief. Those who looked lost and dejected under Brendan Rodgers now look full of confidence and their football is benefiting because of it.
Adam Lallana is one of such players. The England international showed snippets of what he's capable of and what persuaded Liverpool to fork out £25 million for him last year, but overall endured a tough first season at the Reds.
Now, though, he seems to suit Klopp's style of play and is starting to look like the player he once was at Southampton.
Another player flourishing under Klopp is summer signing Roberto Firmino. Bought for a hefty £29 million, Liverpool fans were excited when he put pen to paper, but he started slow under Rodgers.
Known by Klopp from his time in the Bundesliga, the Brazilian looks at home under the German's tutelage. He claimed his first goal over the weekend and appears to be improving with every game.
A major difference already seen between Klopp's and Rodgers' Liverpool is the belief and confidence to beat big rivals. The former has faced some tough fixtures already yet hasn't shied away, beating last year's champions, Chelsea, comfortably at Stamford Bridge and brushing aside City.
Rodgers, retrospectively, failed to beat a top four team until his ninth attempt.
Klopp's reputation alone brings belief and confidence amongst the players; mix that with his tactical genius and positive relationship with Liverpool's players and it's hard to tell how far this side can progress under him.
