The Spanish second seed spoke after a regulation 6-3 6-3 6-4 win over Czech Jiri Vesely in one hour and 53 minutes on Centre Court.
“If he is in the final then I am very excited to play Roger but I am not saying I am not excited to play against Roger in the final. For sure, I will be very excited if I am in that final, it will be a great result for me and facing again Roger will be something fantastic, but if you ask me if I prefer another one (opponent), I say yes.
That’s the point, it’s about being smart, the overall goal is to try to win the tournament and it depends against who you play you have less or more chances to win.”
Top seed Federer earlier strolled into the quarter finals with a 6-0 7-5 6-4 victory over Adrian Mannarino and the two are on course for a meeting in the final on Sunday (July 15).
