I see it as pretty routine stuff for Checo to be kept on for 23 season. It's another matter of fact comment from Marko just to keep his drivers, in F1 or feeder series, putting effort in as hard as poss.
Gasly will not return to main Red Bull seat IMHO, Marko dumped him because he lacks the ability to overtake others in similar of slightly inferior cars. Sure Pierre he has a real turn of speed but that's not enough for top 5 racers, they've got to have the complete package and best others in similar, maybe even better, machines.
Look how Pierre struggled at Imola, he was stuck behind others in similar machinery and went backwards if anything rather than forwards. Compare this to either Tsunoda or Albon's performance in Italy, both went forwards. Q.E.D. I'm afraid.
