The Premier League boasts some of the best managers in the world.

English football may no longer stand out from other leagues in terms of depth, but its coaches are second to none.

How do we judge a manager? Some say it's all about the trophies they've won.

However, playing style, their ability to motivate players and forge a bond with fans, and longevity at the top should all be taken into account.

Whether you prefer a Diego Simeone smash-and-grab, a Jurgen Klopp gegenpress, or the tiki-taka of a Pep Guardiola side is still a matter of preference. 

Fortunately, that's exactly what Ranker is here for, giving fans around the world the chance to vote for the top managers. 

There are undoubtedly some controversial choices who have made it into the top 20, but football is a game of opinions, after all. 

20 - Roberto Mancini  

With the exception of Zenit Saint Petersburg, the current Italy boss has won trophies at every club he's managed. At Manchester City, where he became their first manager in 44 years to win the title, he obviously had a massive war chest. However, he proved in his earlier years at Fiorentina and Lazio - selling his best players and working with a very limited budget - that he's far more than just a chequebook manager. 

19 - Claudio Ranieri 

Apart from engineering one of the greatest sporting upsets of all time with Leicester City in 2015/16, Ranieri probably doesn't warrant a place in the top 20. The Tinkerman has had 20 different jobs since he first ventured into the dugout with Vigor Lamezia all those years ago. 

18 - Joachim Löw

Löw not only won the 2014 World Cup, he did so by transforming Germany's way of playing. The big test will be to see whether he can rejuvenate them after a terrible tournament in 2018. He began his latest phase straight away, axing the likes of Mats Hummels, Jerome Boateng and Thomas Muller and turning to younger talent. 

17 - Erik ten Hag

The Dutchman deserves huge credit for his development of another great generation of Ajax youngsters, many of whom have been sold to generate enormous profits: Matthijs de Ligt and Frenkie de Jong both rose to prominence under his stewardship. He's also turned Ajax back into a European force and won the Eredivisie in 2019. 

16 - Roberto Martinez

The Spaniard's reputation has been on a rollercoaster ride over the years. Impressing as a young coach at Swansea City before winning the FA Cup with Wigan (also getting relegated in the same season), his career took a nosedive in a hapless spell at Everton. Somehow, he ended up with the top job in Belgium, the nation officially ranked as the best in the world by FIFA. We can't help but feel he's indebted to the likes of Eden Hazard and Kevin De Bruyne for making him look good. 

15 - Maurizio Sarri 

Juventus players might disagree with their boss being ranked so highly, at least if reports are to be believed. The chain-smoking, communist former bank manager won a Europa League with Chelsea and he's since taken Juventus to the top of Serie A. 'Sarri-ball' is loved by some, others think it's a pointless succession of passing that doesn't lead to much. 

14 - Zlatko Dalić

A dark horse whose most successful spell as a manager came in the United Arab Emirates, Dalić led Croatia to the World Cup final in 2018. They were the lowest-ranked nation ever to reach the showpiece. 

13 - Gareth Southgate 

Southgate felt like something of a last resort appointment when Sam Allardyce was sacked but he's since overseen England's revival, reaching the semi-finals of a major tournament for the first time in over two decades. 

12 - Fernando Santos 

The Portugal boss led his country to glory at Euro 2016, aided along the way in his current job by a certain Cristiano Ronaldo. In his domestic career, he also won five trophies with Porto. 

11 - Thomas Tuchel 

Tuchel had some rather large shoes to fill at Borussia Dortmund - we'll get to him later. That meant a return of just a DFB-Pokal was a little disappointing. Inevitably, he's won Ligue 1 with PSG but will be judged on how he gets on in the Champions League. 

10 - Massimiliano Allegri 

Allegri has been waiting for the right opportunity to get back into management since leaving Juventus, where he won five successive Scudettos, also winning Serie A with AC Milan in 2011. The 52-year-old might be even higher in the rankings had he won one of the two Champions League finals he's participated in. 

9 - Jose Mourinho 

Having endured a difficult start to life at Tottenham, Mourinho may no longer be at the height of his powers. A CV featuring 25 major honours still makes the Special One worthy of a place in the top 10 and he has had mitigating circumstances behind his underwhelming first few months at Spurs. 

8 - Luis Enrique

The last manager to win the Champions League with Barcelona, Enrique is now back in the Spanish national team hot seat after a break from football following the tragic passing of his daughter. 

7 - Didier Deschamps

A World Cup winner, but we can't help but feel the Frenchman has only managed that thanks to the most talented Les Bleus squad in years, featuring the likes of Kylian Mbappe, Paul Pogba and Antoine Griezmann.

6 - Antonio Conte

The Italian's time in England was short-lived, but he still won a Premier League and FA Cup by bringing back the 3-4-3. He has always been more comfortable in his homeland and he's revolutionised Inter Milan, putting them firmly back in the title race this season even if they're ultimately likely to come up short.

5 - Carlo Ancelotti

Evertonians could hardly believe their luck when he made a shock move to Goodison Park in 2019. The veteran manager has won 20 major honours, including the Premier League with Chelsea, and two Champions League titles with AC Milan. 

4- Diego Simeone

The Atletico Madrid boss might not be everyone's cup of tea, particularly due to his ultra-defensive tactics and the questionable morals with which his side play. While on the whole, this season has been a challenging one for the Argentine, he has earned enough credit by upsetting the duopoly of Barcelona and Real Madrid in La Liga and it's for that reason Atleti stuck with their man.

3 - Zinedine Zidane

The extent to which Real Madrid fell apart without him just goes to show Zizou's career on the bench will likely be as successful as the one he enjoyed on the pitch. Yes, he relied heavily on Cristiano Ronaldo in his first spell at the Bernabeu, but you just can't argue with a record of three consecutive Champions League titles. 

2 - Pep Guardiola

Guardiola will forever be remembered as a revolutionary tactician and a true pioneer. It would be reactive to overlook that on the basis of one underwhelming season at Manchester City. Winning a treble in his first season as Barcelona manager, he won the Bundesliga three seasons in a row before constructing one of the best Premier League sides of all time. 

1 - Jurgen Klopp

Liverpool admired their current boss from afar for years as he won the double with Borussia Dortmund. Now a European champion and on the cusp of winning the club's first top-flight title in 30 years, it's Klopp's 'heavy-metal football', his intense pressing, and perhaps best of all, his motivational skills that set him apart from the rest - in the eyes of the fans, anyway. 

Guardiola might feel aggrieved not to have clambered to the top spot, but Klopp is undoubtedly at the height of his powers right now.
