Rabiot checked out mentally when PSG froze him out and still hasn't recovered.
Danilo found a new role and was rejuvenated. I don't see a new role for Rabiot, he's too one-footed to play regista f.ex.
Good player on his day, but we ain't getting a full consistent season from him. He should leave in the summer and maybe he rediscovers himself again in another league. .
