Alonso and Webber are close. Maybe him and Piastri asked Alonso to not announce his Aston Martin deal until the end of July. So Piastri will be contract free after July 31st and can sign with Mclaren.
Maybe Alpine is an awful place to be behind the scenes and Alonso wants to get back at them.
Rossi seems to be a problem looking at what happened to Prost, Budkowski and Brivio.
This would also explain Fernando’s trolling on social media
It’s all part of EL PLAN
I don't think it will be a driver announcement. In the past, teams rarely issue a time for announcements like this. I think it'll be bigger.
Engine supplier perhaps?
