Whilst I agree that berdych personality isn't one or the most likened tour, I love a good mix up in the top end. Too much similarity and the whole game gets boring. I hope berdych can really upset fully in slams as well, we need to support better tennis and just because federer can't beat a guy doesn't mean we shouldn't congratulate them.
It's about the competition, whoever wins deserves it and we get the pleasure in watching this battles happen.
If berdych beats djokovic, then the top players then will have a serious theeat and the level of play will be challenged.
As for my opinion - I missed the two sets but in the first federer messed up so many volleys it wasn't funny. On top of that his body language was really off, it was quite noticeable. And lastly his forehand was way out of focus, though could of been berdych pace.
