Lewis Hamilton and Toto Wolff were involved in an animated exchange in the Mercedes garage yesterday after another chastening day for the eight-time constructors' champions.
In a chaotic, rain-affected qualifying session for this afternoon's sprint race, in which a record five red flags were waved as cars spun off the track, neither Hamilton nor team-mate George Russell could make it into the final top-10 shoot-out.
Hamilton will line up 13th this afternoon, two places behind his young compatriot and a massive 1.7sec behind pole-sitter Max Verstappen, of Red Bull, who was 0.8sec quicker than Ferrari's championship leader, Charles Leclerc.
It marks the first time in nine years, since the 2012 Japanese Grand Prix, that neither Mercedes car has reached Q3, ending a streak of 187 consecutive races. And Hamilton, still in his helmet, was seen in an animated exchange with his team principal after exiting his car.
"It was all internal stuff and I do not want to share that, but we will keep working," Hamilton said.
