Vettel 'too green for title' - press

Sebastian Vettel is not ready to mount a challenge for the world championship, according to Italy's authoritative La Gazzetta dello Sport.

The sports daily believes the 21-year-old is "too green for the title", as evidenced by his mistake at the start of Sunday's Turkish Grand Prix.

Despite starting from pole position, the Red Bull driver ran off the road on the first lap, opening the door to runaway championship leader Jenson Button.

La Gazzetta said: "The question is no longer whether Button becomes world champion, but when. Vettel is still too green for the title."

Referring to the Istanbul error, the newspaper added: "The Red Bull talent ruined everything with his fourth mistake of the season."

Spain's Marca agreed: "With his driving error, Vettel presented victory to Button on a silver tray."

Ross Brawn was asked by Germany's Auto Motor und Sport about Vettel's mistakes, but also the apparent strategy error committed by Red Bull in Turkey.

"I don't want to criticise my opponents, so all I will say is that they are behind in the championship, so it is logical that they have to take more risks."

In contrast, Brawn's Button is making perfect use of the best car in the field, former triple world champion Niki Lauda believes.

"The package is brilliant. But even then there can still be mistakes but he does not make mistakes. He is fully in control of every situation," the Austrian legend added.

Lewis Hamilton is the youngest world champion in F1's history, and like Vettel has sometimes been accused of making too many mistakes.

Speaking to Bild newspaper, the Briton said of Vettel: "He is only 21 years old and has already won three races. The pressure on him must be enormous, also because the Germans are looking for a new Michael Schumacher."
