Every single driver on that grid strives for two things, to be on pole on race day, and win the race. Every single one of them want that.
Max does it nearly every race.
Why on earth would he leave that to join a team that MIGHT be competitive in a couple of races a season. Unless Mercedes can pull a rabbit out of a hat in some way, that bit of BS doesn't make sense. So there is a photo of three guys talking, so what?
Perhaps in the future, some time down the road, but I don't see it any time soon.
