The “Dutch guy” Klopp refers to is former Wales assistant Raymond Verheijen, who is continuously on social media hitting out at the German’s training methods for causing injuries.
And Verheijen was quick to hit back on Twitter.
The Dutchman said: “Liverpool manager Klopp caused 20 hamstring injuries in 10 months but keeps blaming external factors for injuries.”
Klopp believes the festive overload is also hurting the England national side.
He added: “It doesn’t sound like it is right. Everyone is asking ‘Why England is not too successful in big tournaments.
“Ask what other big countries are doing at this time – they have their legs on the sofa and are watching English football.”
