#5 Jurgen Klopp
Even when Leicester City won the Premier League in 2016 stunning everyone, they had a successful manager in Claudio Ranieri. The Italian won titles in Italy, Spain and France before joining Leicester. This highlights the importance of a winning manager to a title-aspiring side. Jurgen Klopp's presence at Liverpool is, therefore, one of the biggest reasons for Liverpool being capable of winning the title this year.
The German won the Bundesliga twice with Borussia Dortmund against the might of Bayern Munich along with other trophies. He possesses the know-how on building title-winning teams and instilling that winning mentality which the present players at the club somewhat lack.
Brendan Rodgers' inexperience was one of the reasons for Liverpool failing to seal the title in 2014 as they let it slip towards the end. However, in Klopp, the Reds have a top manager who fits in with the club's ethos as well and knows how to get it done.
Hence, when Liverpool get into the final stages of a title fight this season, one can expect Klopp to marshall his troops for conquering the elusive Premier League title.
