Rublev favours this surface but we all know that Djokovic can really adapt at any or even adjust his style in the middle of the game, so really hard to bet on this one, maybe I will try to see the game first if I have the time and just do some live betting.
it all depend on Djokovic motivation to finish early and Rublev serve
maybe it is good to wait for the start, even first point could signal if Djokovic is willing to let first set, he usually start slowly, but he could get motivated after seeing Rublev crashing Tsitsi in first round
over could be fine, if all starts with Rublev good game, but bear in mind that Djokovic could lose 0:2 eventually, he was letting one match in group stage almost every year
My bets arranged by the stake size:
Rublev +2.5 games in 1.set @1.75, this one should be almost free money, especially if Rublev starts on serve
Rublev to get at least a set @2.12
Rublev to win 2:0 @8.6
So first set should be very critical for Rublev here. I'm seeing Rublev might be winning 6-4 first set or over 9.5 @1.95 total games.
