Wow, you are one of those that argue for the sake of it?
First:
Why must a player have said "firepower" to defeat a top player?
Those are your words, not mine. I said Berdych has the firepower of both wings to beat ANY player and not just a top player. Clearly, Novak has step up his game at the GS in the last two years which is saying a lot because he was doing pretty well since 2007.
Novak's game toys with the perfect blend of defense and offense or at least he tries to. In the last two years, his improved physical conditioning and small technical improvements on his serve and and forehand has allow him to exploit this boundary to the very limit.
Which brings us to: what is needed to beat Novak on his best surface? And that is a player that can push the envelop with his own power, thus forcing Novak to defend a little too much instead of attacking. Stan did just that a couple days ago.....firepower of both wings (especially backhand) strong first serve and the ability to keep Novak on his hills. Berdych can replicate this.....Ferrer CAN'T.
Yes, I do tend to argue for the
FucsovicsAny piss in the pot,
Novak has one of the best defense games, so why would putting him on the defense magically make him lose? If anything, his offense struggles more (i.e volleys, overheads, INSANELY tentative shots when he has control). What he actually excels in is going from defense to offense because at that point he builds up momentum to put shots away. Such facts are proven with H2Hs (your favorite stats, no?)
H2H vs. Ferrer 9-5

H2H vs. Berdych 11-1

H2H vs. Soderling 6-1

H2H vs. Wawrinka (Your sexual saviour who you claim has "firepower") 11-2

H2H vs. Cilic 7-0

H2H vs. Andrew "King of Pushing" Mandy 10-7

H2H vs. Pipsqueek "I'm only good on clay, and am a huge pusher" Fixandri 0-1 Ouch.... BURN!
H2H vs. Fabrice "Ima be pushin' 24/7" Santoro 1-1

H2H vs. Antony "Pushing till I'm 102 years old" Dupuis 0-1

H2H vs. Carlos "Pushing on clay all day err'day" Moya 2-2

and last, but certainly not least.....
H2H vs. Rafito "Pushing is tennis, no?" N/Adull 14-19

SO now try and convince me that Chokeovic can only be beaten with mindless ballbashing!
