I would sat 45/55 vs Djokovic and 60/40 vs Berdych but that's just me.
What's the H2H on hard courts out of interest (and also the indoor H2H might be interesting too).
I find Berdych more dangerous indoors than Nole. Also, Andy has already seen a loss to Berdych just last year in Paris. As to Nole, I don't think these two have ever played indoor hard, so this will be their first meeting this week.
We will have to rely on Tsonga a lot to do some damages in this group. Last year, he was able to beat Berdych in the same tournament and Tsonga too is a great indoor player. He's seen some wins over Nole as well in the past, so I feel Tsonga will be more tricky for Nole and Berdych than Andy.
Will be interesting to see how Berdych fares against Nole too.
