This Lewis/Nico is the same as Webber/Vettel - Webber had opportunities to win titles at RB, didn't get the results and Vettel did. I can't see Nico staying with Merc for more than 3 years to be honest - the negativity of coming second to Lewis is already having an impact on track.
Funny how the Alonso/Webber comraderie is being replaced by Vettel/Nico.
