Webber pitted at the end of Lap 7 and took on the hard tyre which only lasted him till the end of Lap 19. Staying out two laps longer had given him the lead, but in the second stint, on the hard tyre, he couldn't shrug off Vettel and surprised commentators by coming in so early. Who was he racing at that stage - Vettel, or the two Mercedes behind Vettel?
Webber wasn't able to make his mediums last as well as Vettel in the second stint. And while Vettel was able to close up on Webber when the Aussie had hards and the German had mediums - when they swapped tyres Vettel was quicker on the hards as well.
The gaps on Lap 23 were:
Lap 23: Webber to Vettel, 2.6: Vettel to Hamilton 2.1: Hamilton to Rosberg 3.3
At this stage Lewis Hamilton was flying with a fastest lap of 1:41.610 putting pressure on Vettel. In fact, the three cars following Webber were all closing in. Webber suddenly slowed down by 1.4 seconds to the cars behind. Thus the gaps on Lap 24 were:
Lap 24: Webber to Vettel, 1.2: Vettel to Hamilton 1.8: Hamilton to Rosberg 2.6
Lap 25: Webber to Vettel, 0.5: Vettel to Hamilton 1.7: Hamilton to Rosberg 2.3
Lap 26: Webber to Vettel, 0.4: Vettel to Hamilton 1.3: Hamilton to Rosberg 2.6
Lap 27: Webber to Vettel, 0.7: Vettel to Hamilton 1.0: Hamilton to Rosberg 1.9
Lap 28: Webber to Vettel, 1.3: Vettel to Hamilton 1.2: Hamilton to Rosberg 2.2
It was around Lap 26/27 that Vettel uttered his dismissive "Mark is too slow, get him out of the way," which sounded exactly like the kind of thing that a 'protected' spoilt boy would say. But the lap times show that Mark was only five laps into his stint on the mediums, could have gone faster, and was backing Vettel up into the two Mercedes. If his intent was to try and run as slowly as possible on a faster tyre than Vettel, then the logical thing would have been to let Vettel through as their strategies were different. Vettel had proved in the first stint that he could make the medium tyre last longer, so why wasn't he let through?
Autosport's Mark Hughes believes that Webber was backing Vettel into the cars behind, just as he had been before their infamous clash in Turkey in 2010. Vettel was irate at not being allowed to run his true pace - because his engineer was soon on the radio telling him not to follow too close in the fast corners - and also aware that the two cars behind him were running on his pace and not Webber's.
