People really need to evaluate the ref objectively. He decided to let things go early on and actually remained consistent with that throughout for once.
It wasn't a definite yellow from hwang but it could have been. however, he could also have booked both ake and kovacic before that incident for worse and choose not to. Then towards the end, Doku gets a second yellow all day if the hwang one was a second yellow, he didn't give that either so he's remained consistent which is all we want.
No issues with the ref at all today. Anybody trying to blame the ref for defeat today needs to take the blue tinted specs off.
