Arsenal, who have been badly hit by injuries and suspensions in recent weeks, received another huge blow with the news that Robert Pires will miss their Champions League match against Bayern Munich at Highbury next week.
The French winger will be out for up to three weeks with a sprained ankle he picked up in Arsenal’s 1-1 draw with Southampton on Saturday.
“It doesn’t look like anything is fractured,” Wenger told the Arsenal website.
“But it is a good ankle sprain. It does not look like he will be ready for two to three weeks.”
Arsenal, 3-1 down after the first leg of their first knockout round tie in Munich last week, have been hit by injuries.
England defender Sol Campbell is still unavailable and Brazil’s Edu is doubtful with a pulled hamstring.
“Sol will be out for two more weeks,” said Wenger. “It is open for Edu. The earliest is Bayern but even then there is a question mark.”
Thierry Henry is another suffering from injury and the French striker will definitely iss Tuesday’s FA Cup replay against Sheffield United.
“Thierry is out with an Achilles problem…Therefore I have to think about who I play up front,” Wenger added.
To compound their injury problems, Arsenal are also with Dennis Bergkamp and Jose Antonio Reyes who are both serving three-match suspensions as well Dutch striker Robin Van Persie who was sent off at Southampton on Saturday.
