Vettel's selfishness probably cost Red Bull a podium in China. I'm not complaining, I'm an Alonso fan, but with only 3.5 secs separating Alonso and Ricciardo at the end, if Vettel had let Ricciardo through when he was asked Ricciardo probably would have been able to take the podium off Alonso. It's too early to say yet, but the belief of some drivers and fans that Vettel needs a car advantage to give his best may prove to be true. Both Hamilton and Alonso have proven to be able to wring the neck of a poor car achieving very good results, the same doesn't seem to apply to Vettel, not yet at least, we will know by the end of the season. It's worth pointing out that in Ricciardo's hands the Red Bull is proving to be a very good car.
