Djokovic 2.30
Federer 8.00
Nadal 8.20
Zverev 9.50

Tempted to place a bet on Zverev, nice odds, I believe Federer is done physically, same for Nadal (will too rusty at least), while the favorite is Djokovic I think it's time for Zverev to step up and go far, maybe capitalize on an early crash for Nadal or Federer.

Zverev won the ATP finals while he was at odds 20 before the tournament, it's time to back him to win a slam.

Any constructive opinion welcome.
