Liverpool manager Jurgen Klopp has turned around the Reds' fortunes after taking over from Brendan Rodgers in the beginning of October and this has begun to worry former Manchester United manager Sir Alex Ferguson. They have qualified for the last 32 of the Europa League and made strides in the Premier League, including convincing wins over Chelsea and Manchester City.

The Merseyside club were one of the form teams until this weekend before they suffered a shock defeat at the hands of Newcastle United, which dropped them from sixth place on the Premier League table to eighth.

The Anfield outfit, however, are just three points behind fifth-placed Tottenham and six behind United, who are going through a barren spell after failing to win their last three games in all competitions. The Scottish manager, who won 13 Premier League titles with the Old Trafford outfit and always ensured they finished above their arch rivals, is worried about Liverpool's sudden rise and has admitted that he does not want the Reds overtaking the 20-times English champions on the Premier League table.

Ferguson also praised Klopp for his personality and is confident that the former Bosussia Dortmund manager will make a difference at Liverpool during his reign. "I'm worried about him because the one thing United don't want is Liverpool to get above us," Ferguson said, as quoted by the Daily Telegraph.

"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," the former Red Devils manager added.
