Robin van Persie's critical comments about the role of his Netherlands team-mate Arjen Robben will not have a negative effect on the team, Robben insists. Van Persie set up the Chelsea forward for the only goal in the 1-0 win against Serbia & Montenegro on Sunday in Group C but later complained that too much of the game had gone through Robben.

"There was no malice in what he said. This is not an issue," Robben said yesterday after a light work-out in the scorching heat. The Arsenal player insisted he had merely stressed the need for optimal teamwork. "They turned a molehill into a mountain," he said. "It was taken out of context.

Van Persie had said: "(Robben) needs to take his team-mates into account. Sometimes he makes choices that are good for himself but not the team. We all need to realise that we are doing this together. We had several chances against Serbia & Montenegro but against the really big countries you maybe get one chance, and precisely in this situation you have to make the right choice. He cannot do it on his own."

In contrast, Robben's former PSV Eindhoven and Chelsea colleague Mateja Kezman had positive words about the 22-year-old.

"The season when I was there (at Chelsea) Robben showed a lot and I think he was the best player at Chelsea in that season," said Kezman. "Then the last one he had problems with the coach, and I'm sure he deserves more respect. When Robben plays like that (against Serbia & Montenegro) he is the best in the world in that position."

Paraguay goalkeeper Justo Villar will undergo a scan on his right leg to discover whether he will play any further part in the World Cup.

The Newell's Old Boys custodian suffered a nightmare start to the tournament, conceding an early goal in the opening Group B defeat against England on Saturday, before tearing a muscle on the inside of his right leg after only seven minutes.

Paraguay's team doctor Osvaldo Pangrazio confirmed Villar will miss the remaining group games against Sweden and Trinidad & Tobago and, depending on the scan results, could sit out the rest of the competition.

The doctor also revealed Diego Toledo's thigh injury could keep him out of Thursday's clash with Sweden in Berlin and warned: "We must be very careful, because it's a muscular injury."
