No further punishment for Ferrari in team orders scandal
Jenson Button is concerned that this season's world championship will be tainted if Fernando Alonso wins by less than seven points.
Alonso currently leads the championship by eight points, seven of which were gifted to him by team-mate Felipe Massa when he let Alonso into the lead at the German Grand Prix. Ferrari was fined $100,000 by the stewards after the race for breaching the ban on team orders, but the FIA decided to take no further action during a hearing in September.
If Alonso finishes second at this weekend's Abu Dhabi Grand Prix he guarantees his third world title, but Button reckons he needs to do it by seven clear points to avoid a public outcry.
"I just hope if he wins it then he does so by more than seven points," Button told the Sun. "Some will be disappointed with what happened at Hockenheim and question whether he deserves it. I don't care who wins it really.
He said he approved of Red Bull's decision to let its drivers to decide their fate, even if it means losing the title to Alonso.
"I like the way Red Bull let their drivers fight," Button added. "That is the way it should be. You fight all the way through your career to get into F1, to get into a good car, to win races. If you still have a chance of winning the world championship, you should be given equal opportunities and it is good to see they have said that is important.
"I don't know who will win, it is very close. I'd say it is between Mark Webber and Fernando."
