Red Bull boss Christian Horner says the team are not taking any comfort from Ferrari's reliability issues, as he insisted the title race remains wide open despite Max Verstappen's lead.

Ferrari are 56 points behind Red Bull in the constructors' standings despite Charles Leclerc claiming his first victory in eight races at the Austrian Grand Prix last time out, while Verstappen continues to lead the Monegasque star in the drivers' championship.

With Carlos Sainz triumphing at Silverstone, Ferrari have posted back-to-back wins for the first time this season but have been hampered in their bid to compete with Red Bull by issues with their car.

Sainz looked set to make it a Ferrari one-two in Austria before a dramatic engine failure left his car immersed in flames.

Meanwhile, Leclerc struggled with throttle problems as he held off Verstappen for the win in Spielberg, admitting it was cause for "concern" after the race.

But Horner says Red Bull cannot rely on Ferrari's problems in their bid for a first constructors' title since 2013.

"We are not too focused on them [Ferrari]," he said, looking ahead to Sunday's French Grand Prix.

"We can't control or contribute to that in any way. I think that we've got to focus on ourselves and just getting the best out of our own package.

"They had a very strong car [in Austria], and they could have finished first and second."

Meanwhile, despite Verstappen having a 38-point lead over Leclerc in the drivers' standings, Horner thinks the title race remains wide open, as he praised the team's "damage limitation" efforts last time out.

"We are just at the halfway point of the championship and things swing around quite a lot," he added.

"There is still an awfully long way to go. I would say Austria was sort of damage limitation, as we managed to get the pole, get the sprint victory and see the second place [in the race].

"I think Max has only lost five points to the Charles in the drivers' championship and obviously damage has been relatively contained in the constructors."
