Red Bull's Max Verstappen finished fifth and Charles Leclerc of Ferrari took fourth.

Speaking after the race, Norris lauded Sainz Jr. "Carlos was very generous helping me get DRS," he told David Coulthard in a post-race interview, via the BBC.

Red Bull ended up off the podium for the first time since the Brazilian Grand Prix last November.

The Austrian team had won 15 successive races until Sunday, but that looked set to end from the moment they failed to qualify in the top 10.

The final top 10:

1. Carlos Sainz (Ferrari)

2. Lando Norris (McLaren)

3. Lewis Hamilton (Mercedes)

4. Charles Leclerc (Ferrari)

5. Max Verstappen (Red Bull)

6. Pierre Gasly (Alpine)

7. Oscar Piastri (McLaren)

8. Sergio Perez (Red Bull)

9. Liam Lawson (Alpha Tauri)

10. Kevin Magnussen (Haas)

Starting on pole, Sainz kept the field close enough to remove any pitstop window for others, managing his tyres before helping former team-mate Norris stave off the chasing Mercedes by letting him stay in DRS range.

Mercedes' George Russell, pushing hard for the win on far fresher medium tyres than the leaders, crashed on the last lap while in third place - with Hamilton inheriting the podium position and also taking fastest lap.

"We nailed the race," said Sainz after his second career win for Ferrari and first since Silverstone last year.

"We did everything we had to do. We did it perfect and we brought home a P1 that I'm sure all of Italy and Ferrari is going to be proud and happy about today.

"A safety car forced us to pit even earlier than we wanted and I knew it was going to be a long stint and hard

"It was just quite tight at the end, but we gave Lando a bit of DRS to help him - and in the end, we made it P1."

Russell, speaking after the race about his crash, added: "I think we were half a car's length from winning the race, had I got past Lando when I had the opportunity. I think we would have been able to get past Carlos.

"Then just the last lap, a millimetre lapse of concentration and game over."
