Sir Alex Ferguson worried about Klopp factor at Liverpool
Jurgen Klopp's appointment at Liverpool has left Sir Alex Ferguson "worried" the German will elevate the Reds above Manchester United.
Ferguson famously stated his biggest challenge upon arriving at Old Trafford in 1986 was to "knock Liverpool right off their perch" and by the time he retired in 2013, he had guided United past the Reds' record 18 domestic titles.
The last of Liverpool's championship victories came prior to the Premier League's formation but, after hiring Klopp in October and losing just two of their 12 games since, Ferguson is confident the ex-Borussia Dortmund boss will transform the Merseysiders' fortunes.
Speaking at the TechCrunch Disrupt London event, Ferguson said: "I'm worried about him because o ne thing United don't want is Liverpool to be above us, that's for sure.
"He's a fantastic personality, he's got that great confidence in himself.
"I noticed in yesterday's game when they lost the second goal he went across to (Newcastle boss) Steve McClaren and was smiling and congratulated him - it was class, that.
"He's got a great personality - his big white teeth are always showing he's enjoying it. I know him quite well from the coaching seminars we have and I got a text from him the other day.
"He's going to make a difference to that club, there's absolutely no doubt about it. He's got the personality, he's got the drive, he's got the knowledge and a great presence about him so I think things are looking up there."
