Djokovic v Dimitrov
The number 1 seed, 2011 Wimbledon Champion against the 2014 Queens Champion who upset the defending Wimbledon Champion.
On paper, Djokovic is the heavy favourite.
However, Dimitrov has the tools to trouble Djokovic.
Novak doesn't like big servers. Grigor has a strong 1st serve? Tick.
Novak hates variety (e.g. Federer's slice). Grigor has a good slice and can play variety? Tick.
Federer v Raonic
Federer is good at dealing with big servers with his chip/block returns but can he deal with Milos, the 'Missile', Raonic?
On paper, yes but the Raonic serve on grass is even a bigger weapon so there could be some tight tiebreaks.
Will the young guns be able to breakthrough? Will there be a changing of the guard(s)?
Or will the multi-slam champions prevail like usual?
