It comes as no surprise that Lewis Hamilton and Nico Rosberg didn't have the strongest of relationships during their three years as 'teammates'.
Both drivers spent the 2016 season focused on being the Formula One World Champion.
Lewis was looking for his fourth title, while teammate Nico was looking to secure his first World Championship title.
But, almost a year on from the shock retirement of Hamilton's ex-Mercedes teammate, he has labelled Rosberg "negative".
It's looking like Lewis is close to signing a new three-year contract with current team Mercedes, worth an estimated £120million, and in an exclusive two-part interview with SunSport's Ben Hunt, the three-time Formula One World Champion has opened up about his feelings towards ex-teammate Nico Rosberg.
Despite Rosberg no longer being a threat on the track, it has not made things easier for Lewis, but it has made the environment a better place to work in.
“It has not made things easier for me but it has made the environment a better place to work in.
“When you remove a negative and then replace it with a positive — it is like having a circuit-board and you have a bad fuse, that’s the whole frikkin unit gone. When you replace that fuse, the whole thing works again."
Hamilton went on to say: “I am still pushing myself to new limits. He could be here and I’d still be driving like this and he knows it.
“It’s like when you have been in an unhealthy relationship. You only stay in it because you love that person.
“It is not until that relationship ends and you get further down the line you realise, ‘S***, that relationship was not good for me’."
It became a shock to everyone when Nico announced he was retiring at the end of the 2016 season, and that must have been frustrating for Lewis, who finished runner-up to his ex-teammate.
Although, things seem to be going well for Lewis and new teammate Valtteri Bottas, it seems the heat with Rosberg has simply moved on to Ferrari.
Lewis said: “We are now positive as a team. The hurricane that was built within this team is now blowing towards Ferrari.”
For Lewis, the next focus now is winning the title in Austin on Sunday night, or next week in Mexico.
In doing so, he will become the first British driver to win a fourth Formula One World Championship, strengthening his mark as the nation's 'greatest' driver.
“It definitely means a lot. What does it mean to me winning a fourth world title? It is difficult to say until you have got it because you don’t know how you will feel."
Hamilton added: “I don’t know if you even notice but when I am on the podium and when I look back and see the British flag, I am very proud of it and I hope people see that... It is a very humbling experience.”
