I am not saying they should drop Sordo completely, but I am questioning that they should offer him 8 starts.

With regard to Suninen pairing with Sordo. One big point against it is that Suninen actually has pretty bad record from the fast rallies where Sordo is bad.
Best is 4th from Finland 2017 and only once since then has he been in any podium fight on them (Sweden 2019). Two WRC2 fastest rallies in Finland but that's against much less competition. His actually best results are from slow gravel.
