Switching jobs and getting accustomed to new surroundings is always a challenging task and if you happen to be a manager of an esteemed football club, the job gets a lot more difficult.
While managers like Pep Guardiola, Jurgen Klopp, and Massimiliano Allegri have done tremendously well with their clubs, here, our focus is on the men who were handed the reins of their respective clubs at the start of the season.
Here are five newly-appointed coaches who have done impeccably well, so far, this season.
5. Marcelo Bielsa - Leeds United
Considered as one of the most influential managers in the modern era, Marcelo Bielsa has taken the Championship by storm since taking over Leeds United in June. His signature explosive style of play has worked seamlessly so far, as most of the other teams have found them almost impossible to contain.
Currently, Leeds sit just a point behind league leaders, Norwich City and have a five-point cushion in the hunt for automatic promotion.
4. Unai Emery - Arsenal
Despite Arsene Wenger's bleak ending to his Arsenal tenure, Unai Emery had a lot to do in order to justify his appointment. Back-to-back defeats to Manchester City and Chelsea in his opening two matches didn't help his case, but since then, the Spaniard has truly turned the corner.
Saturday's late victory over Huddersfield extended Arsenal's unbeaten run to 21 games, showing how quickly Emery has settled in at the Emirates. They are currently fifth in the league, trailing fourth-placed Chelsea by goal difference.
3. Maurizio Sarri - Chelsea
Following the bitter end to Antonio Conte's Chelsea tenure, Maurizio Sarri was appointed with renewed optimism and expectations and so far, it's safe to say that the Italian has done a pretty great job.
The Blues look effortless for the first time in decades, which should be chalked down to Sarri's intricate style of play. Fourth-placed Chelsea arguably delivered their most convincing performance of the season on Saturday, beating defending champions, Manchester City, 2-0, at Stamford Bridge.
2. Thomas Tuchel - Paris Saint-Germain
It might look easy, but managing a dressing room full of such combustible characters is no mean feat and newly appointed Paris Saint-Germain boss, Thomas Tuchel, has done brilliantly on that front.
Despite showing some nerves in Europe, PSG have been absolutely ruthless in Ligue 1 this season. In just 16 games, they have picked 44 points and are sitting 13 points ahead of second-placed Lille with a game in hand.
1. Lucien Favre - Borussia Dortmund
Bundesliga is one of the most monopolised footballing leagues in Europe. However, looking at how things are shaping up this season, it would be surprising if we don't get a new champion at the end of the campaign.
No one expected Lucien Favre's Borussia Dortmund to confront Bayern Munich's superiority in the manner they have, this season. Not only have they been racking up the points, but they have also looked impeccable doing it. They currently sit on top of the Bundesliga table, nine points ahead of Niko Kovac's Bayern.
