He admitted in interviews before that he wasn't planning on playing much on clay this year.
So he'll probably play Dubai, one of the IW/Miami and then at most one clay master before RG, will get top-8, not more.
No one really knows his plans and he could change his schedule as he likes so it could fit his aims or goals or what ever. Maybe that is why he has not said anything about clay season. 1st he would like to be fit and healthy for FO and Wimbledon.
We need to see how it is going next months .
