Former Wales and Manchester City fitness coach Raymond Verheijen has slammed the methods of Liverpool boss Jurgen Klopp.

Verheijen has a history of attacking the training methods used by some English clubs - including similar criticism of then Manchester United boss David Moyes after an injury suffered to Robin van Persie.

Along with Klopp, he also questioned the work of Chelsea's Antonio Conte.

Verheijen tweeted: "In past weeks media reported how intelligent coaches like Conte & Klopp do 'too much too soon' with double & triple sessions in pre-season.

"Coaches destroy players by training too much too soon in pre-season in 3 phases: 1) fatigue phase, 2) injury phase & 3) injury crisis phase."
