Given how badly we had ballsed up the Cole situation, the Gallas save was a good one. Gallas (and Carvalho) had saved Terry at Chelsea. The problem for Gallas is the same problem that guys like Vermaelen have at Arsenal. Wenger neglects defense, so even good players look shit.
Sturridge for Walcott? Won't be an enormous improvement, but I wouldn't have to see Theo's face. Sturridge is more direct, has more tools for getting past his man, but also has a tendency to take bad shots when there are others in better positions.
