MADRID (AP) — Novak Djokovic is optimistic about his game going into the French Open despite going another week without a title. The top-ranked Djokovic is yet to win a trophy this season while trying to regain his best form after not being allowed to play in the Australian Open because he was not vaccinated for COVID-19. Djokovic lost to young sensation Carlos Alcaraz in three sets in the semifinals of the Madrid Open on Saturday, when he was trying to make it to his second consecutive final after losing to Andrey Rublev in Serbia last month.
