It was interesting to see in Arsenal's 2-0 success against Liverpool that Theo Walcott was not seen as a useful weapon. Alex Oxlade-Chamberlain and Spanish star Cazorla were clearly the more potent attacking weapons. When Oxlade-Chamberlain was taken off, it was Aaron Ramsay that came off the bench instead of Walcott.
Some people may argue that was a tactical decision and Walcott would have made an appearance if Arsenal were chasing the game. Nevertheless, there are plenty of reasons why Theo should fear for his Arsenal future.
