Nationality is probably the last thing I worry about when picking tennis players.
I'm sure I've already said it many times before but Its a mixture of game and personality on court that drags me.
Most of the Germans have single handed backhands and were always aggressive players in general.
In the beginning I was only really rooting for players who use 1hbh. I always found 2hbh to be too girly
Now I'm more open mined about it, as there are just too many 2hbh's, so there are exceptions that I like such as Tsonga, Berdych, Safin in the past etc etc.
When I first started following tennis my fave was Becker, then Henman and Haas. So basically even though I was living in Yugoslavia back then (now 2 countries: Serbia and Montenegro) I already had my favorite players based on their game. Its simply long before Djokovic arrived on the stage and even though I have huge respect for Novak I can't root for him when he faces my players. Its simply because of the game style.
p.s. Yeah btw, Novak is regarded as god here, and probalby the best serbian athlete of all time. However there's too much ignorance regarding it. Could write a book if I start talking about that.
Lets just say at least 60% of his 'fans' here don't follow tennis. They are fans because he's serbian and he's #1 even though they don't watch him.
It was the same with Ana, when she was #1 everyone thought she's the best of all time because of that, but when she started falling down, they all started making fun of her pursuing modeling career etc etc..
