Arsenal striker Nicklas Bendtner will miss Tuesday's Champions League tie against Olympiakos after he was involved in a car accident. Gunners boss Arsene Wenger, speaking at a press conference on Monday, revealed Denmark international Bendtner suffered a minor crash on Sunday. 'Nicklas did not practise because he had a car accident on Sunday,' Wenger said. 'Fortunately there was no real long-term damage, but he was bruised and we thought it better he did not train. He should be back for Sunday's game (against Blackburn).' Bendtner, 21, was driving along the A1 towards South Mimms when his car left the road. It is understood no other vehicle was involved in the incident and a Hertfordshire police spokesman said: 'We were called at 10.15am to a report of a single vehicle road traffic collision. 'A black Aston Martin vehicle had left the road. The driver was not seriously injured.' Wenger will also be without Brazilian midfielder Denilson, who faces up to two months on the sidelines with a fracture to his back. Goalkeeper Manuel Almunia is still troubled by the chest infection, so young Italian Vito Mannone will continue in his place.
