Christian Horner believes Ferrari's rapid turnaround is indicative of what can be possible for the ailing Red Bull team after another frustrating weekend in Malaysia.

Following a disappointing start to the year in Australia, Horner hit out at power unit partners Renault for failing to deliver a reliable and fast powerplant for the RB11, before calling on the FIA to equalise the engine regulations to prevent another season of Mercedes dominance.

However, the very next race would see Mercedes defeated comfortably by Sebastian Vettel in the Ferrari, a performance that was subsequently hailed as significant for F1 by Horner and Mercedes' Toto Wolff.

Indeed, though Red Bull fared no better at Sepang - finishing a lap down on the leaders and behind both Toro Rossos -, Horner says its effort shows what can be done potentially.

"It demonstrates that everything is possible," he said. "Ferrari has done a good job and things can change quite quickly. We have just got to focus on our issues and address them in the forthcoming races."

Horner also took the time to congratulate former driver Vettel for his comprehensive performance in Malaysia, calling it a classic performance from the German, who won 38 F1 races with Red Bull.

"On a personal note it is great to see Seb win. It was classic Sebastian - got his head down at the front and managed the tyres. He managed to make a two-stop work when others couldn't. Obviously the Ferrari looked very gentle on its tyres in this heat and temperature, but I am very pleased for him and he looked a happy chap."
