Djokovic leads the head-to-head against former world No 3 and 2014 US Open champion Cilic 17-2, but admitted it would be a hard task to overcome the strong Croatian squad members – especially with the world No 1 doubles pairing in their arsenal.
He continued: “As I said, you know, these guys are great guys. I have known Cilic, and we have had some big encounters over the years. I know him very well.
“Borna Gojo is one of the biggest surprises of competition, winning two out of two matches, beating Sonego in Italy, which was a very impressive win. He’s someone that is very young and just has a big serve, big game overall.
“Of course they have the best doubles in the world, Mektic, Pavic. They are winning most of the matches they are playing. We saw some of the matches in Davis Cup they have played so far, and they are winning comfortably.”
