Webber ?had to? make three stops

Red Bull team principal Christian Horner said his team had no option but to put Mark Webber on to a three-stop strategy, because a differential problem with the car meant his tyre wear increased dramatically. Webber's hopes of challenging higher up were dashed when he was hit with the differential failure late in the race - and that problem resulted in more wheelspin which increased his tyre degradation. That led to the team electing to give him a late stop for tyres - even though in theory the better strategy was to stick to a two-stopper
