Alex Ferguson's 'worry' about Jurgen Klopp and Liverpool is coming true

It's safe to say that Jurgen Klopp has made a significant impact on both Liverpool and the Premier League.

And it's something former Manchester United manager Sir Alex Ferguson warned about several years ago.

Klopp arrived at Anfield in 2015 with the Reds hoping to fight back at the top end of the league - and it seems there was interest from United around that time.

Fast forward four years and during the current international break, Liverpool are sitting pretty at the top of the tree.

It has not been all roses for Klopp, who oversaw Liverpool's defeat in the Champions League final in 2018 to Real Madrid but the fact that they got there was a massive plus and set them on the road to glory.

Then last season was something to behold for all concerned with Liverpool as they amassed 97 points in the Premier League and won the Champions League.

Liverpool fans might not have predicted just how successful the German was going to be at Anfield, but United great Sir Alex Ferguson certainly talked of his concern all of three years ago.

"He has done a really good job and revived Liverpool's enthusiasm," Ferguson said of Klopp back in 2016.

"It can happen that big clubs lose it. For two decades, Liverpool changed managers without building their own identity.

"You can now well and truly sense that you have to count them in this year. You can see Klopp's dedication on the sideline, I'm convinced his work in training is similar.

"He's a strong personality. That's absolutely vital at a big club.

"I'm worried about him because the one thing United don't want is Liverpool to get above us."
