Piastri had been leading the grand prix, two seconds ahead of his team-mate, when McLaren strategists decided to undercut the Australian at the second round of pit stops in order to protect the team one-two.
They did so in the faith that Norris would hand the position back to Piastri and allow the 23-year-old to claim his first-ever grand prix victory. However, Norris pulled out a six-second gap to his team-mate, prompting rather emotional radio pleas from his team.
However, the team have come in for criticism for the way they handled things, including from Schumacher, who won six grands prix during his career.
“Yes, it’s a learning process, no question about it, but the main mistake was once again the strategy," he told Sky Germany.
"There was no need to bring Lando in beforehand. If they could have done things differently, it wouldn't have happened at all. Quite the opposite, if Lando had started, you would have seen a race if they had wanted to. Otherwise, nothing. That's the temptation as a racing driver.
"It's clear, how stupid do you have to be? You put your foot on the gas, drive ahead and then you say, let him come. I'll wait anyway, I'll let him pass when he's there. So everyone would do that."
