Jurgen Klopp is on the brink of history. Closing down Manchester City for the Premier League, and looking forward to a Champions League quarter-final against Porto. The double is still on for the Reds and the fans reading this will be absolutely loving it. 

Of course, a double for Liverpool this season will be classed as incredibly optimistic by anyone outside of Merseyside. Still, you wouldn't want to tell Jurgen Klopp that, considering the talent he has available. Indeed, the Liverpool boss will feel that his team can go all the way in both competitions and there is no doubt that the team will fight until that final whistle is blown.

But just how have Liverpool gone from top six bottle jobs, to being on the brink of English champions? It certainly hasn't been an easy ride for the German or his squad.

With the obvious problems seeming to be constantly pointed out for Liverpool. Jurgen Klopp addressed each one perfectly, fixing his defensive problems with big #4 Van Dijk, and attacking problems with #11 maestro Mo Salah.

However, there has been so much work gone into midfield recruitment that seems to just go under the radar, so here's a couple of signings made that really have helped the Reds:

Georginio Wijnaldum 

When signed, everyone wondered why a relegated player would be important to a club the size of Liverpool, Not Klopp. He saw something in the then 25-year-old and wanted him in his midfield. Well, what a choice!

Since signing, the Dutch international has not only proven that he has what it takes to perform in the Premier League, but he has shown that even when new players come in, he is too good to lose his place. Since becoming a mainstay in the Liverpool side, the now 28-year-old truly has shown all of the doubt in his ability was for nothing.

James Milner 

This has to be the bargain of the decade.

Nobody thought James Milner would lift Liverpool the way he has. Coming in from Manchester City on a free transfer, everyone thought he was nothing more than a bench warmer if someone were to get injured. He has been quite the opposite.

Proving to be captain worthy on and off the field, let alone providing countless assists in the Premier League and Champions League, James Milner has been an integral part to this Liverpool side ever since he stepped through the door, and earnt the right to be called a fan favourite.
