Uhmmm... I know some Fedfans won't enjoy my post here, so sorry folks, but I post my sincere opinion, and not what I think folks would like to read/hear...
Judging on the 'form' Fed has shown this week - his total lack of any consistency in serving as well as making TONS of UEs - Murray has his preferred tactic spelled out for him here, i.e., PUSH the old man to death.
, "Ah, mission accomplished, Unforced Error #XX!"
Should Murray in stead decide to leave his brains out with Kim, combined with Fed suddenly being able to teleport his 1st serve from the beach in Dubai and cutting out the UEs, perhaps there's hope for Fed, but for now, my verdict will be Muzza in two or three.
And yes I hope I'm wrong on all accounts.
