Lose any of those and I reckon Silva's toast. 4 points and progression to the next round of the cup minimum, I'd say. Though if I were Brands, I'd be looking for evidence that Marco is learning from his mistakes and changing his approach accordingly. I hope he is using this interlude as an opportunity to seriously think about a way to fix what's been going wrong. More of the same is just not acceptable.
I hope he turns it round, I really do, but I fear stubbornness will do for him.
