In the confusion over their incorrect tyre pressure at Monza, Mercedes neglected to inform Lewis Hamilton that Nico Rosberg retired during the race with the World Champion only finding out in the press conference.
Hamilton won Sunday's Italian Grand Prix by 25s ahead of Sebastian Vettel from Ferrari with Felipe Massa third for Williams. However, for most part of the race it looked like the second Mercedes would also finish on the podium after Rosberg fought back from a horror start.
Rosberg, who had problems with his car during FP3 which resulted in the team reverting to an older engine, was P3 and pushing Vettel hard for second place when his engine blew up with a couple of laps of to go.
The German's DNF means Hamilton increased his lead in the Drivers' Championship to 53 points, but the Mercedes team didn't tell the Brit about his team-mate's retirement as they were too busy focusing on the impending visit to the stewards' office over incorrect tyre pressures at the start of the race.
When asked about increasing his lead in the standings, Hamilton said: "I don’t understand…"
He was then informed that Rosberg retired and replied: "I wasn’t aware of that. Oh. Wow. I think our performance, my performance, I have to really take my hat off to my team: they’ve done a remarkable job the last two years and I can’t thank them enough.
"The constant attention to detail. Improvements they’ve been doing back at the factories in Brackley and Brixworth is just… I’ve never seen it before. Incredibly grateful for everything they’ve done."
