Ange Postecoglou has revealed that Micky van de Ven's continued absence has included Tottenham seeking outside help to understand the stresses of his extreme speed on his hamstring muscles.
Van de Ven has not completed 90 minutes since October, when he came off in a Carabao Cup tie against Manchester City.
He suffered a recurrence on his return against Chelsea in December and played 45 minutes against Elfsborg on January 30 and has not appeared since.
'It is just him understanding his body,' said Postecoglou. 'You look to the experts in that space and there are people looking at it in different ways, because he is an elite athlete, but he is also at the extremities of speed and with those athletes you look at how they perform at the optimum level without putting their body at risk.
