Dominic King from the Daily Mail tells us why Dejan Lovren deserves such immense credit for turning his Liverpool career around and becoming a vital cog in the backline.

Mention Dejan Lovren's name in relation to this Europa League campaign and, in a flash, you will be taken back to the quarter-final with Borussia Dortmund.

More accurately, you will start to think about injury time and looking at the clock in the Kop to see if hope remained.

Then you will remember Daniel Sturridge's skill and awareness, James Milner's energy and a high, hanging cross that Lovren leapt to plant at the back post, sparking pandemonium.

The significance of Lovren's header might not have sunk in yet but, potentially, in years to come it will be spoken of in the same glowing terms reserved for David Fairclough's run through Saint-Etienne's defence in March 1977 or Steven Gerrard ripping the Olympiacos net out in December 2004.

Most people do not get to experience those moments when fantasy - how many times did you score a last-gasp winner in front of the Kop in your back garden? – becomes reality but Lovren, on an extraordinary night in April 2016, did. He will have the memory for a lifetime.

This observer's stand-out image of Lovren, however, comes from the second leg of the semi-final against Villarreal. It happened in the 13th minute, when Liverpool had just taken a 1-0 lead but were conscious that one false move would put them back on the brink of elimination.

Spotting the opportunity to launch a counter-attack, a ball was pumped forward by Villarreal's defence for Cedric Bakambu to use his pace and chase. From the press box, you could see the pitch open up as yellow shirts peeled away and those in red tried to keeps tabs on them.

If Bakambu had taken control of the ball, danger loomed. But, before he realised what had happened, Lovren came thundering in: bang! Bakambu was sent spinning like a top, Lovren rose with the ball and Liverpool were back on the front foot, so much so Adam Lallana almost scored.

Prowling in his technical area, Jürgen Klopp celebrated the tackle like a goal. Pumping his fists and roaring his delight at those in the Paddock behind him, the manager's approval was clear but so, too, was that of the crowd. On a night that demanded a clean sheet, Lovren would not be beaten.

Anfield's audience loves skill and flashes of inspiration but do not ever underestimate how much they relish a tackle to change the course of a game. And this was a proper tackle. Full-blooded and immaculately timed, there was never any debate Lovren was going to emerge with possession.

It was, if you will, the tackle of a £20million defender. This is now what Lovren looks and in that instant - as Klopp bellowed and Bakambu landed in a heap and the stands shouted "get in Dejan!" - you could not help but think of how far he has come.

Back in August, remember, when West Ham came and ransacked Anfield for the first time since 1963, Lovren's horrible mistake had gifted them a goal in a 3-0 win. His confidence, at that juncture, was gone and you wondered how things would turn out for him under Brendan Rodgers.

The man in the opposite dugout, though, made a sage point.

"He was overconfident and that can happen," Slaven Bilic, West Ham's manager, explained. "I put him in the Croatia team when he was very young. I know him best. When he's thinking only about his own game, not about the left-back or whoever is alongside him, very few centre-halves are better than him. If you are telling me that Liverpool lost because of Lovren, it wasn't down to him.

"It was a mistake, but a lot of Liverpool players made mistakes. He can be a strong person but if you get kicked in the head every day it's hard to stay strong. It is all down to confidence."

Lovren would be the first to admit his confidence plummeted during his debut season on Merseyside because of issues with fitness and form but, like so many others, he has benefited from working with Klopp. Now he is authoritative and commanding and clearly relishing life.

He will be enjoying it even more if he returns from Switzerland this week clutching a piece of silverware. Should that be the case, Lovren would have done as much as anyone to make dreams come true. Cedric Bakambu would testify to that.
