According to Red Bull advisor Helmut Marko, Nico Hulkenberg was close to being Max Verstappen’s teammate in 2021. Red Bull opted for Sergio Pérez for the season in which Verstappen won his first championship, after his outstanding victory at the 2020 Sakhir Grand Prix. At that time, the team was looking to replace Alex Albon and had been impressed by Hulkenberg’s substitute appearances due to COVID-19.
Pérez’s time at Red Bull lasted until last season, where he was replaced amid irregular results, although he achieved five victories for the team in four seasons.Pérez won that race in Bahrain, and that’s why everything changed in Pérez’s favor.

I think it would have been a really nice moment, because the two of them get along very well, and yes, Hulkenberg is a safe bet for points, and in our car he would also have been in high positions.
