Arjen Robben and Robin Van Persie left Guus Hiddink’s training session early raising concerns about possible injury ahead of Holland’s crucial Euro qualifier against Kazakhstan.

Reports suggest the pair trained for half an hour with the main squad but left after that raising doubts about their fitness. There has been no official confirmation regarding this from the Dutch national camp but Van Persie’s sluggish start to the new campaign does raise concerns regarding his fitness.

Van Persie has been showing signs of improvement with every match he is featuring in but is still not having the same influence he had in his title winning debut season with the club. The Manchester United striker was given an extended summer break by former Holland manager Louis Van Gaal following his contribution in the World Cup. While the break was no doubt fully deserved, it meant that Van Persie was short of match fitness during the start of the new Premier league season. The former Arsenal man looked sluggish during the early weeks adding to the Red Devils’ early season troubles in which they collected only two points from three games.

Despite a quiet August, the 31-year-old felt he was coming back to his best and told BT Sports few days ago, “I feel very good to be fair. If I compare when I started the first couple of weeks and to where I am now and how I feel now, it’s a big, big difference.”

He showed more of his former self while netting in the 5-3 loss against Leicester City and also in the 2-1 win against West Ham but just as his potentially devastating partnership with Colombian striker Radamel Falcao was beginning to mature, this reported new injury scare could be another setback for him. Manchester United fans would be hoping that this is a minor knock which will not result in a lengthy layoff for the Dutch striker.

Holland face two important qualifiers against Kazakhstan and Iceland in the space of four days and Guus Hiddink will no doubt look to use the star striker for these matches which could potentially aggravate his injury. Holland are desperate for points after going down 2-1 against Czech Republic in the opening game of Group A. Ron Vlaar is still absent because of his calf injury and the recent injury scare concerning Van Persie and Robben will not be good news for Hiddink ahead of this crucial tie.
