Jamie Carragher has revealed that Sir Alex Ferguson was instantly worried when Liverpool appointed Jurgen Klopp in 2015.

The German has been a revelation for the Reds leading them to a Premier League title and a Champions League crown during his time on Merseyside - something he could potentially repeat this season.

Liverpool are still fighting on all fronts at the tail end of the campaign after winning the Carabao Cup in February, securing their place in the FA Cup final and Champions League semi-final, as well as being two points clear of Manchester City in the league following their 4-0 win over Manchester United on Tuesday night.

It would be unprecedented for the Reds to win the quadruple but it's a real possibility as Klopp's men hit top form at the perfect time. It was impossible to predict that Klopp would have been such a huge success, but Ferguson seemingly had an inclination that he would do well.

The legendary Old Trafford manager approached Carragher at Michael Carrick's testimonial just after Klopp was appointed and said he was "worried" about the German being in charge of United's rivals.
