Did Arsenal miss a trick? Why no Walcott?

I suppose that it did not matter in the end, as Arsenal were able to soak up the pressure from West Ham and record a vital away win that keeps the little run of results going and moves the Gunners above the Hammers in the Premier League table.

However, it was not exactly smooth sailing and on another day we could have been talking about another draw. It should have been more comfortable for the Arsenal players and fans as well, as we should have killed the game off in the second half.

Alex Oxlade-Chamberlain had a good game and I am not having a go at him, but he was clearly tiring as the second half wore on and Wenger had the perfect replacement on the bench in the shape of Theo Walcott. And the fact that the Ox is just back from a groin strain meant keeping him on made even less sense.

Not only is Theo quicker than the Ox, but he is a better finisher and would probably have taken at least one of the chances we made.

I realise he is not fully match fit yet but how is he supposed to sharpen up without any time on the pitch. Maybe the boss was saving his subs for defenders but he only used two anyway. Why not give Walcott a run out and try to finish the game and thereby take away the need to defend for our lives in extra time? If we were still at 2-1 with a few minutes left, you could always take him off again.

What do you think Gooners, is Wenger being TOO cautious with Walcott?
