With Kolo Toure suspended and William Gallas unlikely to feature against his old side, the Arsenal manager can ill-afford the absence of another centre back. Unfortunately Djourou picked up a hamstring problem during Wednesday's 0-0 draw in Porto. However when Wenger spoke to Arsenal TV Online the following afternoon, he hinted the Swiss international could recover in time.
"William Gallas is a big question mark, Johan Djourou is a small question mark," he said. "All that will be assessed on Friday morning or Saturday morning at the latest.
"I am reasonably optimistic for Djourou and a little bit less for Gallas. William has a scan today. That will tell us whether we can go further with him or he has to slow [his recovery] down."
Arsenal TV Online subscribers will be able to see the full interview with Arsène Wenger on Friday morning. In it he talks about: the all-important draw in Portugal, the side he chose for that game, next week's draw, the importance of the Chelsea game in the title race, the threat of Didier Drogba, why Andrei Shevchenko has struggled this season, his thoughts on coming up against Ashley Cole for the first time, the circumstances surrounding his transfer in August, Gael Clichy's step up this season.
