On Friday, ahead of Liverpool’s clash with Tottenham Hotspur, Jurgen Klopp took a dig at his opposite number’s non-illustrious playing career.
During a presser he asked people to Google Mourinho’s playing position and said: “Jose was a goalkeeper, I think. Does anybody know the position of Jose Mourinho? Don’t blame Klopp if you don’t know. I want to know, google it! I have time.”
Incidentally, Mourinho was a midfielder but never really made it as a player.
Klopp too was a decent player who played as a forward, and later a defender who famously said: "I had fourth-division talent and a first-division head. That resulted in the second division."
It's fair to say that both men will always be remembered for their illustrious management careers.
LIVE with Jürgen Klopp as we preview tomorrow's Premier League meet with Tottenham Hotspur ⚪Posted by Liverpool FC on Friday, January 10, 2020
Seven months on from last season's Champions League final, Liverpool and Tottenham lock horns once more on Saturday as two clubs heading in very different directions.
Victory in Madrid last June has sparked Liverpool onto even greater heights. Jurgen Klopp can do no wrong as his side travel to London 13 points clear at the top of the Premier League with a game in hand and seemingly cruising towards a first league title in 30 years.
Tottenham on the other hand are under new management with Jose Mourinho having replaced Mauricio Pochettino.
The Argentine's achievements in transforming Tottenham's fortunes over the first five years of his time in charge did not spare him the sack after a run of three wins from the opening 12 games of the Premier League season.
Mourinho's appointment provided a short-term bounce as Spurs won four of his first five games in charge, albeit against limited opposition in West Ham, Olympiakos, Bournemouth and Burnley.
But if Tottenham chairman Daniel Levy believed Pochettino was the problem, recent weeks have laid bare the much deeper malaise Mourinho is tasked with turning around.
Spurs have climbed from 14th to sixth since the Portuguese took charge in mid-November, but remain six points adrift of the top four and have won just twice in their last seven games in all competitions.
In stark contrast to Mourinho's most successful spells at Porto, Inter Milan and Chelsea, he has been unable to organise Tottenham into a team that is at least difficult to beat.
Spurs have kept just one clean sheet in his 12 matches in charge, conceding more goals in that time than any other Premier League team in all competitions.
Mourinho now has problems to solve at both ends of the field with the news Harry Kane will miss the majority of the rest of the season after undergoing surgery on a hamstring injury.
Kane adds to a mounting injury list with influential midfielder Moussa Sissoko also out until April, club captain Hugo Lloris expected to be sidelined for another month due to a dislocated elbow suffered in October, while Ben Davies, Danny Rose and Tanguy Ndombele could also miss the visit of Liverpool.
After years of beating the odds under Pochettino with lesser resources than their rivals, the stresses and strains on Spurs' squad have been exposed over the last six months.
The concern for Tottenham is that their fall from grace may not be over yet. Christian Eriksen looks set to leave the club on a free transfer if not this month on a cut-price deal.
Jan Vertonghen is also out of contract at the end of the season and Levy reportedly told Mourinho when he took the job that he would not have funds to spend in the January window.
Just months on from being one game away from winning the Champions League for the first time in the club's history, just qualifying for it next season now represents success.
Liverpool on the other hand look set for a historic season. After also claiming the UEFA Super Cup and Club World Cup since lifting their sixth European Cup, the only doubt appears to be over how many more trophies they will lift by the end the season.
Even Klopp's gamble of fielding a team largely composed of youth teamers paid off last weekend in a Merseyside derby win over Everton in the FA Cup to keep the possibility of winning five trophies in the same season alive.
"The passion and ambition of these players is from another planet," Klopp's assistant Pep Lijnders told The Athletic.
"Winning something big puts more conviction, more trust into everything; subconsciously you feel stronger. There's a real hunger to fight for more prizes."
