As we talked about yesterday I agree with half of the post.
It would make sense to change manager if he wants to try to drive at MSport, Toyota or even Citroen. As his former manager seemingly couldn't work well with Tommi, didn't ever want to bring any budget to MSport and already has Lappi at Citroen.
I don't put much into the testing part, even in the same team Sordo and Loeb have both driven full R5 rallies this year (2 for Sordo). Sordo also drove a rally last year.
