He seems like the best candidate but they'd have to deal with his contract with Citroen, who would probably like him driving the tarmac rallies in WRC2 for them.
I think they should give him some test days, or enter him in French local rallies in WRC1, or whatever they can arrange, to see if he gets along with the car. I think they should have started already.
Or... they have already got Fourmaux in the bag, so no point working with Rossel.
