Liverpool legend Jamie Carragher believes Jurgen Klopp is the difference between the title contenders and Manchester United.

The two teams face-off today at Old Trafford.

Carragher wrote for the Telegraph: "I wrote two years ago that if United had appointed Pep Guardiola they would not be waiting long for the title.

"The same logic applies to Klopp. If he was United's manager, the Premier League table would look very different today.

"Let's not forget, even amid this vast improvement Liverpool still finished below United in 2016 and 2018.

"That sums up why for all the crowing about owners and executives and scouts the most important figure at any club is the manager.

"Get that right and everyone else looks better.

"The truth is, in the story of the modern Liverpool we will talk about the club before and after Klopp's arrival. The club's transformation quickened after he was unveiled in October 2015."
