I don't think there were concerns regarding that. The main issues are Perez's seemingly repeat of a slump and Ferrari closing in on points, potentially costing Red Bull the constructor's championship this year.
Frankly who is at this pointยฟ? With Hamilton and Alonso fading with age, I don't see who can match max over a season. Leclerc, Lando and the others haven't honed their consistency to the level that max has. 2020 and especially 2021 have greatly improved Max's consistency upto the point where he is maximising things every race
