Wales assistant manager Raymond Verheijen has aired his frustrations with Arsenal's backroom staff for failing to prevent their players from picking up injuries after Cesc Fabregas limped off with a hamstring strain in the victory over Stoke City.
The Spaniard is a doubt for the League Cup final on Sunday and joins Robin van Persie on the treatment table with a similar thigh problem, and Verheijen feels the related injuries are a result of inept procedures by the Premier League club's staff.
The Welsh assistant manager – who works with Arsenal's Aaron Ramsey – has previously criticised Arsene Wenger for the way in which he handles players and after Fabregas departed the field on Wednesday night he tweeted his bemusement.
Verheijen posted a link to a story on Fabregas and Theo Walcott withdrawing with injuries and remarked: "They did it again!"
He continued: "Imagine how successful Arsenal could be if they would play with [their] best team for most of [the] season.
"The players deserve better injury prevention."
He went on to add: "How many times does this pattern have to repeat itself before someone inside or outside Arsenal [is going to] wake up and do something about it?"
Arsenal are currently challenging on all four fronts in an attempt to end their six-year wait for silverware but Verheijen doesn't think that the way the players are pushed helps.
He previously told Goal.com “The problem is a lot of people think ‘more is better’ in terms of sessions.
"Traditionally, people assume you have to develop the body first before you play the game.
“They push players to extend their limits to get fitter because they copy the training methods from other sports. In a lot of sports, indeed, more is better such as cycling, running, gymnastics or swimming.
“You have people who make football so unnecessarily complicated. Because of this scientific invasion people stop thinking themselves and stop using common sense. The world of football is brainwashed by fitness language. That’s why I always say, ‘Get back to basics’.
“How is it possible that 10 different clubs have 10 different fitness coaches who use 10 different training methods? Players are the victim of subjectivity. Training methods should not be based on someone’s opinion or past experience. The training methods should be football-specific and use different principles to athletics and hockey.”
He said of Van Persie: "At Arsenal he has suffered several muscle injuries which cannot be put down to bad luck."
