Sebastian Vettel insists he is not worried about Ferrari's reliability-plagued Malaysian Grand Prix weekend, as he believes his team has the situation "under control".
Vettel looked on course to bounce back from his disappointing retirement in Singapore and make a serious indent on Lewis Hamilton's championship lead in Sepang, until engine issues in FP3 and qualifying put his hopes of winning in Malaysia in jeopardy.
The Scuderia's hopes of pulling off a win on Sunday were all-but ended when Kimi Raikkonen's SF70H suffered a similar turbo failure that affected Vettel's car in qualifying on his way to the grid, preventing him from contesting the race from second on the grid.
