Paul Annacone vs Ivan Lendl
Annacone has the experience of helping Sampras win majors. Though he hasn't stuck gold except when Federer beat Novak at RG11 and SW19 12.
Lendl has pushed Murray past his berating barrier. Murray reacted with pushing Novak to the brink in the 12 Aussie Semifinals.
Who do you think will give the best tactics and support that will help prevail Roger or Murray in the end!?
Why fight over who is G.O.A.T., when the world is just an abstract of reality~ http://www.newgrounds.com/portal/view/525347
