Liverpool took an embarrassing defeat in Naples last night, losing 4-1 in the worst defeat for any English side in a Champions League opening game since 2003, and Jurgen Klopp will surely be working hard to understand what is going wrong.

The Reds have had a disappointing start to the season, breaking their own records for all the wrong reasons with the side enduring their worst start in the Premier League since the arrival of their legendary German coach, collecting just nine points from their first six outings in the top flight.

The deflated manager came out in his post-match interview to reveal that Liverpool need to "reinvent" themselves following the humiliating performance against Napoli.

As a result, Klopp must finally ditch veteran midfielder James Milner after seven years with the club as his performances haven't been up to scratch over the season so far and at 36 years old, he shouldn't be relied upon to start in the midfield three.

According to WhoScored, Milner is being dribbled past more than any other player in the entire Premier League this season per 90 minutes (3.8), and it comes as no surprise when you look at his output in the league.

Over six appearances the Liverpool midfielder has lost 69% of his duels combined and loses possession of the ball every four touches, with his poor ball control translating into his awful performance against Napoli last night.

The £150k-per-week dud who is "no longer the answer" according to talkSPORT's Ade Oladipo was the worst rated (5.4) player on the pitch according to SofaScore, committing four fouls including a penalty, winning just three of his 11 duels, completing none of his crosses (0/1) and making no interceptions.

To an extent, Klopp's hands are tied when it comes to deploying a fit and available midfield at the moment with Thiago Alcantara just returning from injury whilst Jordan Henderson, Fabio Carvalho and Curtis Jones are all sidelined.

With that being said, something needs to change and fast at Anfield if Liverpool are to have any hope of picking up convincing results as their pursuit for more trophies is looking more difficult than ever under Klopp.
