I know everyone here knows that Federer's level was worlds above Nadal's in those two sets, since Federer's best level on clay was better than Nadal's. And that makes those two misses by Federer all the more inexcusable.
So which of those two shots do you think was worse? I am addressing Fed fans particularly.
I remember both matches well. The pos was down 2-5 in the first set in Hamburg 2008 and took a medical timeout and down 2-5 in set 1 of RG 2011 he changed his bandages taking way more than the allocated time to deliberately ruin Federer's momentum. Unsporting pos of the highest order. Note the same scoreline in each and when being soundly thumped he had no option but to use his dirty bag of tricks.
Admittedly Federer shouldn't have lost focus but that's easier said than done when your body cools down from stopped play and ruined rhythm. The clowns here proclaiming him a god fail to realize he's done this and other things to Federer A LOT. If he's so amazing and so superior to Federer (in their eyes only btw) then why exactly does he need to do these things? Because he's not. He's gotta try and win some other way when losing. Wimbledon this year again when Federer was serving for the match and Indian Wells 2012 semi when he was serving for the match he runs off to the toilet. A prick. Nuff said.
Re the shots in the poll, who cares. Can't change history but we can remember history and history will remember those unsporting match changing tactics the prick used many times. Those 2 matches in your poll are good examples along with the others I mentioned.
