Jurgen Klopp and Liverpool are a match made in heaven.

The charismatic German took over the reins of the famous Merseyside club in 2015 after Brendan Rodgers was shown the Anfield exit door.

Klopp inherited a team on the slide, but in just one season transformed them, taking the Reds to two cup finals within the first year of his tenure.

Since then, Klopp has flipped the fortunes of the club on its head, turning Liverpool from Premier League pretenders to Champions League finalists, and this year into genuine title contenders.

While their promising lead at the summit of the Premier League has been recently overhauled by Manchester City, the Reds are still well and truly in the running with eight games still to play.

They will also be quietly confident of going one step further in the Champions League having disposed of German giants Bayern Munich in the round of 16.

The impact that Klopp has had on the club is plain for all to see - the players love him, the fans adore him and he has built a side worthy of being considered the best Liverpool side in decades.

However, while Klopp has worked his magic to create one of the most exciting sides on the continent, there is still a very dark cloud that looms over his time on Merseyside.

For all the brilliant football his side has produced, Klopp is yet to win a trophy with the Reds.

Three finals have come and gone and the trophy cabinet is still painfully bare.

And former Liverpool man Stan Collymore believes Klopp simply can not be considered a “great manager” until he has won something with the Reds.

Speaking in his column for The Mirror, Collymore declared that Klopp has to win something if he really wants to cement his place among some of the great names that have gone before him.

“For all the fantastic football and positivity he has brought to the club, however, he still needs to lift some silverware before I can hail him as one of the managerial greats.

“I said a year or so ago that he had to win something this season and, while I’ve slightly revised my opinion on that given Liverpool’s progress, it will be a must next season if we are to judge Klopp as a success on Merseyside.

“If as a manager you finish second a bunch of times, reach a couple of Champions League finals without winning them, and miss out on the League Cup or FA Cup because you haven’t prioritised them, you cannot be seen as a great.”

Good point, Stan.

The pain of losing those three finals will still haunt Klopp, who will be desperate to go one step further and win something for the fans that adore him so.

Immortality beckons for the German and his current crop as they scrap it out for the Premier League title.

If Klopp can lead the Reds to the biggest prize in the land, then there can be no questions about his greatness.
