Liverpool are afraid manager Jurgen Klopp might not sign a new contract amid fears of burn out, the UK Sun reports.
Klopp is believed to earn around £7million a year and Reds owners, Fenway Sports Group (FSG), have made an approach to raise his salary to £10m following success in the Champions League last season.
The German and his coaching staff signed six-year extensions in 2016, keeping them at Anfield until 2022.
However, Klopp values his health far more than money, which is why he is taking his time to make a decision.
On the other hand, FSG are worried that the more successful Klopp becomes, the more attractive he makes himself to big European clubs in future.
The 52-year-old who finished second in the Premier League last season has expressed his intention of ending Liverpool’s 29-year wait for the title.
