I'm looking forward to this. I love the Djokovic/Federer match-up, and it should be 10x better on the grass. Honestly, I'm happy if either wins. I'd love to see Federer win his 18th GS, especially after his rather substandard 2013 season where many, including myself, never predicted he'd win a GS or even make a GS final again. I'd also love to see Djokovic win. He's been in so many GS finals these last 2-3 years, and it's kind of sad to see him always getting so close but not walking away with the gold. You have to admire his consistency, too. He's always performing well at the GSs but seems to constantly drop off in that last match. You can tell he really wants it.
So yeah, I am happy on whoever wins this match. My prediction is Djokovic in 4 sets. There's no denying how well Federer is playing, but I think Nole is going to seize the moment here. This is one of his best chances to win a major, and I think he deserves it. I think he thinks he deserves it, too, so I can see him really up the ante. Then again, this will probably Federer's last huge chance to win a major, so he'll throw everything but the kitchen sink here, as well. Djokovic usually plays rather passive in finals, but I think it'll be a completely different story here.
Something like 3-6, 7-6, 6-4, 7-6 is my prediction. Should be a good match!
