Rantanen.
First of all I would like to say that he is really good.
But on the other hand, if you are not able to match the times of the fastest drivers nationally, how could you match or beat the fastest drivers internationally.
In World Championship rallying you have to be amazingly good in order to succeed, you have to be able to destroy your opposition on national level in order to go further. And that is not Rantanen.
If Ogier is now number one of the list of potential drivers, Östberg and Novikov are there right behind, Rantanen is somewhere outside of top ten.
