I don't see it happening also, but that don't mean I won't support him. He don't have to win AO. Andy has done his share for tennis during the last 10 years. I just hope he can stay healthy for another year or two and make some good matches/tournaments here ot there.
But can he stay healthy 6-7 months? The last 2-3 years every time he had a momentum he got injured. At that point I don't know if can keep himself healthy for long periodes, train hard an prepare at the same time.
Besides, his is serve is not what it used to be. He can not serve his way throgh matches like before. That the reason why he got crushed every time he played top 10 player this year, with the exception of Ferrer match at the US Open.
