I feel for Nyck, but Alpha Tauri was never a good fit for him and he must of known what he was getting in to. He had to be matching or beating Yuki from the start, and he has not done that. He is 28, so he was hardly going to be given as long as the younger drivers coming through.
Perez has been lucky in the sense that he has driven a Red Bull which can make its way through the field, where as Albon and Gasly did not have that luxury, so if they did not get the most out of qualifying, they were stuck. Now Red Bull have a decent car, its easier for Perez to recover when he has a poor qualifying performance.
I would love to see Dennis Hauger get the Alpha Tauri (Name TBC) seat for next season. I think the next half of the season could shape Yuki's career. If he can beat Daniel Ricardo, I think that puts him in a really good place for having his chance in Red Bull next season. I am not sure he is ready for it, but as Danny mentions above, are Red Bull going to want him taking a seat up in the Alpha Tauri, if he is potentially going to end going to Aston Martin in a few years?
It is going to be interesting to see how the driver market shapes up over the rest of the season.
