Fitness coach goes on Twitter rant about Jurgen Klopp

Raymond Verheijen has said Jurgen Klopp's training methods "destroys players."

The former Wales coach regularly decries the training methods of Premier League clubs and managers, and said last December that Klopp's methods would lead to an injury crisis. The following month Liverpool were without 11 players. Verhijen also criticised David Moyes when he was Manchester United manager over Robin van Persie's injury problems. In July 2013 he wrote:

"The only way to solve this problem in Jurassic Park (Manchester United) is to improve education of these dinosaur coaches, fitness clowns & scientific cowboys. All over the world in preseason you see the pattern overtraining-fatigue-injuries'. Always avoid accumulation of fatigue in pre-season."

The Dutchman took aim at Klopp and new Chelsea manager Antonio Conte in a series of tweets on Monday afternoon. Verheijen criticised the methods used by the two coaches, both notable advocates of high-intensity, pressing football. He claimed the pair are overworking their players in pre-season, and putting them at risk of injury. https://twitter.com/raymondverheije/status/754994413777129472?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994521453293568?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994572053340160?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994614461923332?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994657608818688?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994700810067968?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994788223574016?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994887783772160?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754994929995317249?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754995062879191044?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754995103694028802?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754995143527297025?ref_src=twsrc%5Etfw https://twitter.com/raymondverheije/status/754995994572492804?ref_src=twsrc%5Etfw The tweets were sent on the same day that Peter Krawietz, one of Jurgen Klopp's coaching team, explained the club's preseason training methods ahead of their tour to the US.

‘It will be a long season, we know that, because there’s no break until the end of May. We know we have to do nearly everything we need on the pitch, and therefore we train a lot – we train long, we train hard and we train often,’ he added. ‘We have to build the base for the physical shape; we have to try to improve our style of play in defending and offense. We have a lot of work to do and it is very, very important, of course. ‘We will have a look every day and in every session at each player, as much as possible. And we want to use video analysis, to speak with the players, work with them on and off the pitch and give them our opinion if we think it is helpful. We try to make each player better.’
