A bit of conjecture here. The injury news is looking a bit more positive but that might not be what could be worrying Arsene Wenger now.
He has to get William Gallas and Bacary Sagna to refocus on club football after the Ireland France odyssey. Gallas of course was one of the principal characters in the France farce and might be in for some stick with fans with Irish national players in their club like City and Aston Villa. And Arshavin might be feeling blue after the Russian flame out.
Their rebounding from these distractions might pose some problems. Wenger will have to get them mentally ready for the games ahead.
