One of Dejan Lovren's worst performances for Liverpool came away at Old Trafford in 2014, in his first match against the Red Devils.
The Croatian international struggled desperately after signing for Liverpool from Southampton, weighed down and struggling with the £20 million price tag, seemingly losing his confidence.
He was frequently in and out of Brendan Rodgers' XI, but under Jurgen Klopp he has made a big improvement, with an injury crisis causing little option for the centre-back to become a regular starter in the heart of defence.
Lovren last night excelled against Manchester United, highlighting how in recent weeks he has turned around his career at Anfield.
The defender is forming a solid partnership alongside Mamadou Sakho, with the pair giving Manchester United little opportunity as they kept a vital clean sheet in a 2-0 win, ensuring they did not concede a crucial away goal.
The Reds allowed United just one shot on target, with Lovren making a team high six clearances, with one tackle and one interception.
His performance had supporters raving about his turnaround, and buoyant about Jurgen Klopp's coaching ability. Here is a look at how fans reacted on Twitter...
Pleased Lovren has turned it around. Always said he's a quality player just confidence shot to pieces. Our best CB on the ball #lfc— Tony (@crazyitalian7) March 11, 2016
Even if Matip is as good as people are saying, he is not walking into this team with the way Lovren & Sakho are playing together #LFC— Anfield Odyssey (@AnfieldOdyssey) March 11, 2016
How much better is Lovren and the Liverpool defense in general without Skrtel, coincidence? #LFC— Scousermart (@mballard66) March 11, 2016
Lovren and Mignolet 0 mistakes! What a time to be alive!!!!! #LFC— Lemmiwinks (@Revill9) March 10, 2016
Lovren has been a real difference maker. Since Klopp arrived, when fit, he's looked like the player he was at Southampton. #LFC— Mark Robinson (@MrMCRobinson) March 10, 2016
Lovren and Sakho's partnership is the best. Gotta hand it to Lovren, his confidence boost under Klopp has been terrific. #LFC— El Capitán© (@Starklordx) March 10, 2016
