Too soon for Toto Wolff to pick a favourite driver?

When your teenage driver keeps beating your pre-season favourite, what do you do?! Kimi Antonelli won his third Grand Prix in Miami ahead of teammate George Russell and it's thrown up a load of questions at Mercedes.

How is Toto Wolff going to manage the championship now? Should Kimi be treated as the team's number one driver? Could Max Verstappen come sniffing for Russell's seat if he doesn't start winning again?

And later... is the FIA President right to bring back the noisier V8 engines?
