Rosberg is bouncing back to his very best - Wolff

Nico Rosberg will be back to his strongest at the next race in Spain according to Mercedes boss Toto Wolff.

The German has yet to beat his team-mate in qualifying or race trim this season and therefore trails Lewis Hamilton by 27 points after four races.

However a better showing in Bahrain, which Wolff described as exceptional, has led the Austrian to declare that Rosberg is back to his best.

"Anyone who doubted Nico saw Nico at his best fighting hard, overtaking," Wolff is quoted by Autosport. "He did everything right."

Although Rosberg finished third behind Kimi Raikkonen, a problem with his brakes meant he was unable to defend in the closing laps. Without that, Wolff is certain he would have come home second.

"Losing that position because of a brake failure is a pity," he added.

"Without that, I think he was driving so well that he would have kept the Ferrari behind - but he had no weapons to defend.

"So I have no doubt after his driving in Bahrain, which was exceptional, we'll have a very strong Nico bouncing back next time."
