Outspoken fitness expert Raymond Verheijen has taken aim at Manchester United's injury management.
Verheijen was the performance manager for the South Korea national team in the World Cup and has also worked with the Dutch and Russian teams as well as several clubs, including Manchester City, Chelsea, Zenit St Petersburg and Barcelona.
The Guardian says in a series of messages on his Twitter site he expresses his apparent belief that United's fitness staff have "messed up" at a time when 11 players are injured and there are serious doubts about Owen Hargreaves's ability to play at the top level again.
