Red Bull team boss Christian Horner insists there is still a long way to go in the title race despite Sebastian Vettel's current hot streak.
Vettel has opened a 34-point lead at the top of the Drivers' Championship after winning the German Grand Prix while Red Bull are now 67 points clear of second-placed Mercedes in the Constructors' standings.
World Champion Vettel has also won four races this season and he may well have been on a hat-trick of victories if he didn't suffer a mechanical failure while leading the British GP last week.
The German's dominant form has seen him move to outright favourite for the title, but Horner believes the likes of Ferrari, Lotus and Mercedes are still in the hunt for glory.
"It's still very much a four-way battle and you can't discount anybody," he is quoted as saying by ESPF1. "We're effectively at the halfway point of the year and there's still an awful long way to go.
"Anything can change, but to have won four grands prix in the first half of the year is satisfying but it doesn't guarantee anything. From weekend to weekend we see different teams with different levels of competitiveness and I'm sure that will continue during the next few events."
He added: "For us in some ways it made up for the disappointment of Silverstone, having got so close to winning the British Grand Prix; to address that a week later at Sebastian's home race was a great result."
The likes of Ferrari and Mercedes will no doubt be looking to get back in the Championship in Hungary in a few weeks' time and you can visit Paddy Power for the latest odds.
