Well Tsonga does not tend to match up well with Federer but should be an entertaining match regardless.
Haven't seen much of Tomic but is he likely to cause Novak any problems? Credit to Fish as well quietly moving through to the quarters.
Delpotro should almost just go boom or bust on return I feel now, Nadal is just gonna love this match to become more and more physical as nobody is better than him when matches go that way.
