On paper, the Wimbledon 2017 title should be Roger Federer's to lose, but I don't know if it's a closed deal already.
I have seen the other three guys play and they're just brimming with confidence. Tomas Berdych defeated David Ferrer, Thiem and Djokovic with dominating play, he could give Roger a real scare in their semi's.
On the other side, Marin Cilic has been very composed and very methodical in his dismantling of Kohlschreiber, Mayer, Johnson, Muller and Bautista Agut,he really looks like a contender for another grand slam title.
As for Sam Querrey, he knocked out Novak last year, at Novak's peak, and then parlayed it to a semi's berth this year, defeating Murray, Tsonga and Anderson, so his confidence is sky high!
It just means we are going to get two exciting semi's matches.
As for me, Marin Cilic would be my personal pick. It would be cool if he does give Croatia another Wimbledon title.
That would put him one over Goran Ivanisevic!
