Yes Lewis has issues, so did Rosberg. I should have copied a list of his issues that costs points that was on some other website. He was the leader of issues last year.
I can't see Vettel TBH, he seems to have made himself a Ferrari man now, that's my only reasoning. Alonso seems perfect. Best driver arguably, two year contract, for Merc to arrange getting Max maybe.
I wasn't going to make a big deal of the reliability issues... that stuff is just a part of the sport. Yes, Nico had more issues last year, but the title race wasn't even close. (and it was only ever a mathematical possibility in '14 thanks to the crazy double points scheme in Abu Dhabi). This year, it's getting more attention than it normally would for two reasons IMO. 1) It was unusually one-sided. 2) Title race was so close that any one of at least 5 distinct failures "not happening" would have given a different outcome.
Alonso is a very good option - we shall see :-) In some ways, it would be nice to see Merc reward it's test driver or another up-and-comer with the seat, but that wouldn't give us all the spectacle that we want with two top-tier drivers going head-to-head...
Niki Lauda has declared he wants "someone better than Rosberg" so all up and coming drivers can wait in the back room thank you very much. And also he wants the deal done by Christmas.
