That's the problem.
If Ogier wants more rallies how many rallies that are not fast gravel will there be for Lappi? Ypres would be extremely difficult to do well on with very little experience (one start in 2014 with crash from 3rd).
Greece is maybe most likely and again Lappi has little experience there.

Catalunya is a rally Ogier likes (and Lappi has bad record on) and he will want to do Toyota home rally.
