What Lando says here is one of the worst takes you can have after a day like this. I don't know who let him loose on the media pen without a PR person guiding him beforehand, because comments like this are embarrassing.
Max can be a bit of a prick with his tactics on-track at times, but credit where credit is due, the guy is always respectful of rival's performances. This reaction by Lando is that of a spoiled man-child and a bit of a sore loser as well.
Just take it on the chin and move on. The title was not lost today, there were many missed opportunities throughout the year and only one of them could be blamed on Max. The rest should be used for self-reflection.
When he says things like this, he is pretty much inviting all the toxic people to plaster him in social media. And honestly, it's tough to argue against them on this case.
