I wonder if Marian Vajda based his decision to part ways with Novak Djokovic last year,because Novak is unvaccinated?
He also said on (twitter) ...as a unvaccinated player,he will have a limited number of tournaments, and he already has a strong team with Goran Ivanisevic.After considering all the circumstances,we decided by mutual agreement that we would end our professional cooperation.
Well things have changed regarding COVID and vaccinations,Novak will be allowed to play Monte Carlo and Roland Garos this year,also Wimbledon,with other tournaments eg,Rome looking to relaxing their vaccination status.
