At the start of the day, both men had four.

Now one has five, and the other has lost something dear to him.

Those eyes tell a story - that there's a lot of hard work to come over the winter months.

Sebastian Vettel had a great start to the season, and the pair tied on points throughout, but sadly it unraveled for the German.

Do we see a fifth world championship on the cards for Vettel in the future?

Adios amigos.

The five time world champion, has five big moments to share...

Nico Rosberg, who denied Lewis Hamilton the 2016 world title, has posted this video on social media praising his former team-mate.

Kimi Raikkonen drove a storming race last week, and today it looked like Vettel, could be back with that overtake on Ricciardo, and Hamilton. He took second overall, which is his first time on the podium in three disappointing races - the last time he was competitive was in Spa, when he won, but that was months ago.

So, is it the end of their errors?

Perhaps, but it’s too late now.

Sebastian Vettel tells Sky Sports: "I'm looking forward to getting out of here and stop answering questions. There can only be one winner and he (Lewis Hamilton) is the one who deserves it.

"There are still a lot of lessons to learn to make sure we make the right conclusions. We are a very talented and gifted team, we have the most support behind us and very clever people behind us.

"We have huge potential, everyone is fighting hard to make sure we finish the last two races and win the constructors title and knock them off their crown. I will try everything to score as many points as I can."

"He joins the realm of the three greatest drivers." Listen to 5 live commentary to the moment when Lewis Hamilton won his fifth world title.

Lewis Hamilton says: "Throughout the year there was a lot of testing times for us even when we didn't have the package and were on the back foot sometimes, but we had the belief in the team that we could come out with something good even though we went the quickest.

"It took some special laps, and some special moments in the car. I could relive those moments, some of them were magical. I truly believed we could win the championship. So much work has been going on in the garage, and behind the scenes and with strategy and set up and that's been key.

"I feel like I can drive anything and I feel like I can take the car to places that nobody else can and to do that you have tot get the car in the right place, work with the team to unleash the greatness in the car and unleash the greatness in yourself."

Sebastian Vettel says: "It is an absolutely horrible moment, you put a lot of work in. I did pay attention in maths so I knew the numbers.

"Three times in my life I have had that disappointment when you realise you cant win the world championship and those are not happy days. You reflect on the work that goes on from last year to now.

"We had some chances we used some and did not use some. In the end we were not good enough."
