Arsenal striker Nicklas Bendtner could be missing for the first few weeks of the new season as he continues to struggle with a groin injury.
The 22-year-old Denmark international, who played in all three of his country's games in this summer's World Cup, sustained the problem in training last week and missed both games of the Gunners' Emirates Cup success last weekend.
Bendtner is already certain to miss his side's Premier League opener at Liverpool with the injury, but admits he still does not know when he will return to training.
"It is a difficult injury and hard to say when I'll be back, but hopefully I'll be training as soon as possible," he told The Sun.
"We haven't set a date yet, we're taking it easy."
Bendtner's absence leaves boss Arsene Wenger short on numbers in attack with Marouane Chamakh and Carlos Vela the only recognised strikers to play at the weekend, with Robin van Persie only recently returning to the squad following his World Cup exertions.
