#3 Jurgen Klopp's experience

In 2014/15, Brendan Rodgers' inexperience was one of the major reasons for Liverpool's struggles in the UCL group stages. However, this time around, the club has Jurgen Klopp as the manager.
The German built quite a reputation for himself at Dortmund where he led them to the Champions League final in 2013, thumping Real Madrid 4-0 at Westfaldion on the way.
Thus, the manager not only has the experience of building title-winning teams but also possesses the know-how to develop teams capable of conquering the cup tournaments. This is in stark contrast to the previous Liverpool manager in the Champions League and it definitely makes a difference, especially in the latter stages of the tournament.
Thus, the lack of experience on the players front can be compensated by Klopp's, giving Liverpool a great chance to win the top tournament.
