Raymond Verheijen criticises Liverpool and Chelsea's outdated training methods in string of tweets

Raymond Verheijen, the former Wales coach, has strongly condemned the training methods of Jürgen Klopp and Antonio Conte.

The Dutchman, who previously criticised Klopp during Liverpool’s injury crisis last season, has claimed that doing “too much too soon” during pre-season “destroys players”.

Klopp and Conte, Chelsea’s newly-appointed manager, are both known to focus on intense physical conditioning during the summer months, with the intention of regaining full fitness.

Verheijen, however, believes such methods to be outdated and outlined his reasoning in a string of critical tweets.

Verheijen's criticisms

In December last year, Verheijen correctly predicted that Liverpool would suffer an injury crisis in the following weeks and later criticised Klopp for not “adapting his methods to the situation.”

Liverpool were without 11 players in total at the peak of their crisis in early January, with six of those players suffering from a hamstring problem.

Verheijen's latest comments come after a spate of injuries to the club's defence.

Mamadou Sakho and Joe Gomez - who has not played since damaging an anterior cruciate ligament last October - both suffered Achilles tendon problems last week.

Joel Matip, a summer signing from Schalke 04, hobbled off the field with a foot problem during Sunday's 2-0 pre-season friendly win over Wigan Athletic, though Klopp described the injury as "not too serious".
