First, the good news. Arsenal picked up no new injuries after Wednesday's sensational 3-0 Champions League win at Karaiskakis Stadium. This is especially good news considering that Mesut Özil reportedly had to be tested due to some tightness in his calf ahead of the match in Greece.
Furthermore, Alexis Sanchez and club captain Mikel Arteta both are on "short-term injuries," according to the boss. While they won't be available for selection this weekend, AW said that Alexis' injury is "the shortest one." The others, he said, would be available "after Christmas."
The boss also reported that Tomáš Rosický is "quite positive" - the Czech maestro has apparently been "running outside" but is "not ready yet." Wenger estimated his return would be the end of January.
Unfortunately, any hope of Jack Wilshere returning during 2015 seems to have been extinguished, with Wenger saying there is "no chance" he will be back during December. Hopefully, Jack will get a chance to show his stuff in 2016.
