Who remembers 'that' day in Spain when Nico Rosberg and ex-teammate Lewis Hamilton crashed out of the Spanish Grand Prix?

The 2016 Spanish GP was a race that both Mercedes drivers would have wanted to forget.

The pair made contact during the first lap, which resulted in both cars having to retire from the race, and, a couple years later in an uncut video, Rosberg has explained what exactly happened on that day in Barcelona.

"That was a tough day," said Rosberg.

Rosberg, who went on to win the 2016 World Championship was looking to secure his eighth consecutive race win when a 'racing incident' resulted in both him and his teammate Hamilton retiring from the race.

In a video posted on Rosberg's official YouTube channel, he talked us through what happened on that day in Spain.

The German–Finnish added: "I closed a bit late. Lewis went in a bit too aggressive, well a lot too aggressive and I closed too late and that's it.

"Then he spun and I didn't know where he was anymore and then suddenly just pow.

"Something hits me and just takes me right off."

Rosberg went on to explain what happened after the incident between him and the team.

"Yeah and then afterwards sitting in the room, watching the reply on the laptop again just trying to understand better what happened and everything.

"Then we had the team internal discussions and everything and that was real complicated."

The blame for the incident was pointed at both drivers depending on which fans you asked, with some saying Hamilton was too aggressive, and others saying Rosberg shouldn't have made a move like he did.

However, the stewards later ruled it as a racing incident, although it later became clear that Rosberg was 'de-rating' leading up to the accident.

Rosberg had accidentally entered an incorrect engine mode, which meant going into Turn 3 his car was significantly slower than his teammates, causing him to 'get the de-rate'.

Rosberg explained: "Outside of Lewis, normally that always goes wrong, but I said I'll try it just one more time and then I got the de-rate."

It was a tough day for Rosberg, as not only did him and his teammate retire from the race, but it also meant he didn't get that eighth consecutive win.

He added: "I was also gutted because I had won seven races in a row at that point, and this was gonna be my eighth race in a row...

"...I think Vettel's record was nine, so that was a real pity."
