Top fitness coach Raymond Verheijen has slammed the training methods of the England squad.

The former Wales assistant manager, who is advising Russia at Euro 2012, suggested Roy Hodgson and his staff were overworking players and putting them at risk after the groin injury suffered by Manchester City's Gareth Barry.

The Dutchman wrote on Twitter: "Groin injury for Gareth Barry. Roy Hodgson: 'We had three tough days in training.' Which amateurs are in charge of the England periodisation?

"Roy Hodgson: "Phil Jones & Ashley Young felt hamstrings tighten so we removed them as a precaution." Jurassic Park at international level."
