Former Manchester United manager Sir Alex Ferguson has admitted that he is worried about the positive impact that Jurgen Klopp has made since becoming Liverpool boss.
The Reds have lost just two of the German coach's first 12 games in charge, with the latest coming at Newcastle United on Sunday.
Having taken United beyond Liverpool's record of league title wins during 26 years in charge at Old Trafford, Ferguson has suggested that former Borussia Dortmund man Klopp could steer the Merseysiders back to the top of English football.
"I'm worried about him because the one thing United don't want is Liverpool to get above us," the Scot told The Mirror.
"He's a fantastic personality, with those big white teeth always showing. Even at Newcastle when they lost the second goal he goes over to Steve McClaren to congratulate him. That's class, that. And the work he did at Dortmund.
"I know him quite well from the coaching seminars. He's going to make a difference at that club with his personality, drive and knowledge. Things are looking up there."
Liverpool are currently seventh in the Premier League table.
