It was only three years ago that Liverpool finished second under Brendan Rodgers.

However, after the departure of Luis Suarez, things started to decline for the red half of Merseyside.

Jurgen Klopp stepped into the hot seat in October 2015 and a wave of optimism followed the enigmatic German to Anfield.

But, after spending around £150 million (with Naby Keita's large fee to come) in two years, how far has the Liverpool side come?

We take a look at Klopp's XI from the 0-0 draw with Spurs, his first game as Liverpool boss.

Simon Mignolet

The Belgian is still fighting for the No.1 spot at Anfield, but was recently 'rested' for German Loris Karius.

Nathaniel Clyne

The England international is currently on the shelf and with a serious back problem, will remain there for the foreseeable future.

Martin Skrtel

After eight years with Liverpool, the 6'3" defender finally left Anfield and headed to Fenerbahce in the summer of 2016.

Mamadou Sakho

The former PSG man left the club for Crystal Palace this summer despite, arguably, being the best defender at the club. His relationship with Klopp was strained.

Alberto Moreno

Things haven't always been easy for the Spaniard at Anfield and found himself on the bench watching make-shift replacement James Milner last season. After a decent preseason this year, he's back in the fold.

Emre Can

One of Liverpool's brightest young talents. The 23-year-old continues to grow with every season, but his contract is up in 2018.

Lucas Leiva

After spending a decade with Liverpool, Lucas finally departed the club this summer and now plies his trade with Lazio in Italy.

James Milner

The versatile England international has remained a constant in the Liverpool side under Klopp whether it be in defence or midfield.

Adam Lallana

The former Southampton man has really flourished under Klopp and, when fit, he epitomises the pressing ethos that Klopp loves.

Philippe Coutinho

The crown jewel. Barcelona were desperate to steal the Brazilian this summer but Liverpool resisted some monstrous bids for their star man.

Divock Origi

The Belgian is now on-loan with German side VfL Wolfsburg after failing to score regularly enough to impress at Anfield.

So, what's really changed at Liverpool? Only four of that eleven are no longer at the club (three, pending Origi's return next season) and the one problem areas most fans believe they have - defence - is the one place Klopp has actually properly replaced.

The question is, is Joel Matip and Ragnar Klavan the answer?
