While Socceroos coach Pim Verbeek says he has "no worries" about the result of the friendly meeting in Eindhoven, the former South Korea coach has conceded Blackburn midfielder Grella is likely to miss the trip to Tashkent for the opening World Cup qualifier on September 10.

Grella suffered a calf injury in training and was seen on crutches on Friday.

"Vincenzo has had an MRI scan and it doesn't look good," Verbeek said. "It is going to be very difficult for him to be ready for Wednesday."

Defender Mark Milligan will not feature against the Dutch and is 50/50 to be available to face Uzbekistan, but Verbeek has declared Galatasaray midfielder Harry Kewell as "back."

"Harry is fit, Harry is ready, Harry is fresh," added Verbeek. "It is good to see him in the group."
