Arsenal have had two surprisingly bad results in the last two games while Man U have are in ominous form. But is it really worth the massive swing in the betting odds? I'm very reluctant to second guess these odds but at the same time I can't shake the feeling that I "knew" that Man U was a steal a few weeks ago.
I suppose these markets depend on people with knowledge similar to mine acting on it and setting them straight. This is what has happened I suppose, but I still think it took a little long and I don't like having my blind faith in markets shaken.
