Vettel less than half a second down on softs, let's remember. Less than 3 tenths behind Lewis on that tyre.
On super soft, he seemed to be caught in traffic middle sector + massive mistake in final sector so we can't judge based on that. No idea what Kimi was doing on ss but it's barely an improvement on Vettel's soft run, so there's definitely more to come there.
Still , even if the soft tyre gap is representative, that would be disappointing - I expected closer than 0.5 here. We'll see but button's time is encouraging since it makes me think that Mercedes' gap is largely due Ferrari issues, since they're not that far clear of a midfield McLaren.
