Liverpool legend Jamie Carragher has confessed he has a 'nagging fear' over how long the Reds can continue their successful run once Jurgen Klopp and sporting director Michael Edwards leave the club.
Carragher claimed there is no other manager that could have achieved the success the German has since his arrival at Anfield.
The pundit hailed Liverpool as one of the best-run clubs in world football under FSG's management but believed the biggest influence on the Reds was the manager.
The 54-year-old's contract with the club is set to expire in 2024 and he revealed last year that he intends to take a year's sabbatical when his tenure at Liverpool comes to an end, with retirement even a possibility.
