Re: Dimitrov or Tomic?
In 4 years Federer will be gone, but I could easily see Djokovic, Murray, del Potro and Nadal (health allowing) still winning GS titles. So it's not a must that some these younger guys have to win them. Having said that I like Dimitrov the best from this group (Tomic, Raonic and Goffin being the others).
All animals are equal but some are more equal than others
