Situation in the ATP rankings:
N Djokovic – 1st
M Cilic – 9th
N Djokovic has won three matches in straight sets at Wimbledon and only in the latest match against K Anderson he had some problems and needed five sets to win the match.
Cilic was far from perfect so far in the tournament as he had many problems in the match against Berankis and was lucky to escape with a win, he also needed 5 sets in the match against Isner and dropped a set in the latest match against Kudla.
N Djokovic and M Cilic have met once this year and Djokovic has recorded an easy win with the score 6-0 6-3. He has won against Cilic at Wimbledon last year and I predict another easy won for N Djokovic.
