I think it is in terms of their talent and good hands that both Gasquet and Dimitrov are compared to Federer. Neither of them play like him though...
Gasquet is a naturally defensive player - much like Nadal, though when he's confident and attacks, he's more effective.
Dimitrov, though his shots look similar to Federer's, plays more like Djokovic in my opinion...have you seen his flexibility?! It's crazy...
