Assuming he wins Miami then he has a chance if he can replicate his 2019 clay season. Made SF at Monte Carlo and finals at Barcelona after beating the likes of Tsitsipas, Djokovic, Nishikori and other clay courters like Jarry and Vinolas.
2 SF at Madrid and Rome this time around could be enough to seal it before RG assuming Djokovic doesn't make any of the clay master finals. Considering Djokovic can also meet Nadal or Them(if fit) as in semis makes it a bit more difficult for Djokovic.
Though it may not last long depending on his results after Wimbledon.
