Jurgen Klopp replaced Brendan Rodgers earlier this month after the Northern Irishman's reign ended after a 1-1 draw with local rivals Everton at Goodison Park on October 4, and the charismatic former Borussia Dortmund coach has re-energised a fan base that had begun to slip into apathy.
The German, who drew his first match away to Tottenham last week, takes charge of his first match at Anfield on Thursday as the Reds host Rubin Kazan, and a white-hot atmosphere is expected to be afforded to the ex-BVB man.
Ex-United star Hargreaves, who honed his trade with Bayern Munich in the Bundesliga, is acutely aware of the qualities that Klopp will bring to Anfield, and the former England international feels that the superb man-management style of the Reds' new boss can get the 18-time league champions firing once again.
"He's a super coach," Hargreaves told BT Sport. "But you see him putting his arm around the players and the younger players, and those nowadays are a bit more sensitive than they were in my time, so you can't really work with that authortarian style.
"The players are too sensitive. Social media and agents all have an impact, but Klopp finds a way to motivate players, and he's very emotional and he gives them the relevant information.
"He's the modern football coach and I think all players love playing for him because he gets the best out of the them."
Daniel Sturridge will be absent with a knee injury against the Russian side, but the England forward's omission is a precuationary one, with Sunday's meeting with the Southampton expected to be the return fixture for the injury-plagued hitman.
Dejan Lovren, Roberto Firmino and Christian Benteke are all back in training and could feature at some stage, but the Merseysiders are without youngster Jordan Rossiter.
