Red Bull appears to be in a difficult position now. They have lost the edge the car had and the others around them are developing their cars faster and they have more development time. I have a feeling that Max might scrap to WDC, but the WCC would be gone soon. With Mercedes also having made progress, Perez can now barely get into Q1, even on his best weekends and probably more often starting from Q3 group on normal weekends. The recent upgrades (downgrades?) have taken the car far away from him. This once again appears to be a 2019/20 type of handling of the car. Max is hitting walls to extract performance and the second driver is crashing regularly while fighting with the lower midfield.
It's going to haunt Horner that he made a huge mistake of retaining Perez. Atleast the best course of rectification now is to swap him with Tsunoda.
