LONDON, Aug 23 (Reuters) - Jens Lehmann has injured his Achilles tendon and will miss Saturday's home clash with Premier League leaders Manchester City, Arsenal manager Arsene Wenger said on Thursday.
The goalkeeper aggravated a chronic injury during Germany's 2-1 win over England at Wembley on Wednesday, Wenger told a news conference.
Wenger said: 'Jens is out and he will miss two weeks, I think. Maybe more. I don't know. He is going to see a specialist in Germany tomorrow. He had this injury before but it has got much worse.'
Wenger said Lehmann joined an injury list that included captain Frenchman William Gallas, with a groin injury, and Ivory Coast defender Emmanuel Eboue, who has an ankle injury.
Wenger said Spaniard Manuel Almunia would replace Lehmann on Saturday for a fixture in which he hopes Arsenal will end City's unbeaten start to the season.
Looking ahead to City's visit to the Emirates Stadium, their first with former England coach Sven-Goran Eriksson in charge, Wenger said it was too early to say if City would be able to maintain a challenge at the top.
'It can last but we will know more after 15 games, then we will have a better idea,' he said. 'I think we have to be patient a little bit.'
He agreed that he was surprised at their confident start to the season and three straight wins.
'When you sign a lot of players, more than three or many more, then it usually takes time for them to click. But they have super-clicked and done so super-quickly as well.'
