Even though Lando Norris completely dominated the Singapore GP, a couple of former Formula 1 drivers still had some criticism for him.

"When you're so far ahead, you should actually be driving relaxed," said Jan Lammers, who is also the boss of the Dutch GP, in an interview with NOS.

Even McLaren CEO Zak Brown admitted that he had to step in during the race by radioing his title-contending driver, warning him to stop making small mistakes on track.

"Tired, happy and tense," Brown described his feelings after the race.

"Lando came close to the wall a few times. He asked over the radio if we saw him hit the wall. I said 'Yes, don't do it again,'" Brown added with a smile. "But he drove brilliantly. He was flying."

2016 world champion Nico Rosberg cautioned Norris, suggesting that if he doesn't learn to calmly bring a dominant car to the finish line, he could jeopardise his championship hopes.

"It's very strange," Rosberg commented to Sky Deutschland. "Unusual.

"You're so far in the lead and you make three mistakes. Twice it was so close to the wall that it was almost over."

"He brakes far too late and locks the front tyre. Normally you're done, the front wing is broken, and the victory is gone. That was incredibly lucky," the German added.

"If he really wants to become world champion, he has to eliminate this kind of behaviour. If you've got the same speed as the guy behind and a 30-second lead, it's not hard to bring the car home."

Lammers, however, conceded that relaxing too much while leading with a big gap can also be dangerous. "Especially if you're good on these street circuits, you get into a flow."

"Then you ease off, mistakes can happen. You suddenly become very aware of everything you're doing. That's why I think Lando was pushing for fun," Lammers concluded.
