No stranger to criticising Man United's training methods, former Wales fitness coach Raymond Verheijen saw fit to lay the blame for Luke Shaw's hamstring injury at Van Gaal's door. Naming double sessions and trying to get the former Southampton star up to match condition too quickly as the factors behind the Englishman's injury woe, Verheijen took to his favourite medium of Twitter to air his grievances against the Dutchman's regime at Old Trafford. Finding a correlation between the Netherlands' niggling injuries during the World Cup, Verheijen labelled Van Gaal's methods as culpable: "At Man United, in the first few weeks, LVG has applied the same approach and, as expected, with the same result: accumulation of injuries. "The Luke Shaw case is the climax of Manchester United's predictable pre-season injury crises due to 'too much training too soon.'" "LVG is tactically superior to most other coaches, but planning and periodisation is not his strongest point: double sessions and muscle injuries." Having been a stern critic of former United boss David Moyes, Verheijen doesn't appear to be taking his gaze from Old Trafford, with Van Gaal his new target.
