Sirmacis should easily be able to win championship next season if he manages to find a budget for the whole season. His only real contender from the guys who competed this season is Lukyanuk, Kajto in my papers can't challenge for it if there is any "potential" driver/s racing for the whole season. only reason he won this year is the fact that he drove every round and Lukyanuk being dumb at few races.
We will see who manages to drive the whole season next year but im pretty sure we're going to get a new champion.
Wouldnt even be surprised if Sirmacis would start to race in WRC 2, maybe even with factory Skoda since they are going to need someone to replace Lappi.
