Jurgen Klopp's Liverpool have endured a difficult start to their season. After humbling Arsenal at Anfield in late August, it has all gone downhill for the Reds, losing Sadio Mane to injury and managing just two wins in their last ten games.
Liverpool's defence has ben nothing short of woeful at times this season and their much revered attacking line-up, who have misfired on occasion too, have been unable to score enough to compensate for the leaky backline.
It seemed as though the Reds may have turned a corner after thrashing Slovenian side Maribor 0-7 in the Champions League, but after Tottenham made frighteningly light work of Klopp's side, it seems they are back to square one.
Now, Liverpool will welcome newly promoted side Huddersfield Town to Anfield as they look to put a difficult period behind them. However, what makes this fixture all the more interesting is that the Terriers are managed by Klopp's close personal friend David Wagner.
The two played together at Mainz, worked together at Dortmund, and Wagner was even Klopp's best man at his wedding. Wagner however, had always played the role of understudy to his good friend, managing the Dortmund reserves while Klopp was given the reigns of the first team.
Wagner got his first shot at full-time management with Huddersfield and guided them to the Championship playoffs in just his second season having finished way down in 19th in his first.
The Terriers won out in via a nerve-wracking penalty shootout to complete one of the greatest underdog stories in recent history.
Now, as the two prepare to face each other in opposite dug-outs for the first time, Jurgen Klopp has revealed how he reacted when he watched his good friend's side complete perhaps the club's greatest achievement.
"I was nervous like hell," Klopp said.
"And afterwards, Ulla [Sandrock, Klopp's wife] sent him a video of me crying like a baby when it happened, the final penalty, as I could not stop."
Jurgen Klopp has always to struggled to keep a handle on his emotions, and so it comes as no surprise that the bespectacled German reacted in such a way.
Wagner's side will be confident of causing a few surprises after downing Manchester United last weekend.
With Huddersfield only one point behind Liverpool in the standings, bragging rights between the two friends are definitely up for grabs.
Jurgen Klopp might be crying for a very different reason if Huddersfield can effect yet another upset.
