Despite both British outfits being amongst the most successful in F1 history, a raft of topics left them battling near the base of the grid 2018 as their rivals stepped up their own game.

Brawn, who is f 1’s managing director of motorsports, reckons that if some title-winning team like Mercedes has benefited from huge stability, staffing re-shuffles in McLaren and Williams over the past few years contributed with their woes.

“Mercedes still have the same people I found therein 2007 and that is more than 10 decades of stability,” Brawn told Motorsport.com. “That’s so important.

“I presume Williams and McLaren, they went through changes and it always takes a while for those activities to settle down. They truly have been terrific teams having a fantastic historical past, but unfortunately Formula 1 isn’t a fantastic respecter of histories. It simply respects what’s happening.

“We as Formula 1 very much want the teams to receive back into a competitive position because they are wonderful teams and wonderful brands. But Formula 1 has no mercy.

“If you’re not doing a firstclass job you it’s demonstrated every Sunday or any Sunday. They’ve got capacity to get back into a competitive place, however it is really a tough job.”

Brawn also believes that a lack of equilibrium in Ferrari, that lost its president Sergio Marchionne at the middle of last year, led to its collapse to secure the world championship .

“I presume there wasn’t any doubt with Ferrari, the passing of Sergio Marchionne had an effect.

“It was tragic in itself however, it also had an impression on this team. For a person of the calibre and standing, it’s definitely going to become considered a very destabilising situation for some time.

“But I think that they are going to have viewed exactly what they’ve learnt and Sebastian [Vettel] would consider exactly what he has done. I think there’s a solid chance they will probably be there fighting [in 2019].

“You have to check out the Ferrari of a few years past to realise just how much progress they’ve made. The very fact we are discussing them coming near winning a tournament is rather a accomplishment over at which they were two or three decades back.

“It is such a enormous struggle to even win in Formula 1. But to secure a tournament is just another amount. So, you can talk about every team that will not win the championship as using its challenges.”
