F1: Vettel, don't celebrate with finger, advises former champion Alain Prost

ABU DHABI (REUTERS) - Alain Prost has one piece of advice to offer Sebastian Vettel, from one four-time Formula One world champion to another.

It has nothing to do with driving, with the Frenchman recognising that Red Bull's 26-year-old ace needs little help in that area, and everything to do with how the German celebrates after winning.

"If I see him, I am going to give him the advice to stop celebrating with his finger," Prost told reporters at the Abu Dhabi Grand Prix, where Vettel is chasing his seventh win in a row.

Vettel's raised single digit has become a trademark of his celebrations and a particular annoyance for those who would rather see someone else win.

Prost expects the German to be in a position to make the gesture for some time to come. Next year sees significant changes to the regulations, with a new turbocharged V6 power unit with energy recovery systems, and he expected the new era to favour Vettel as much as the old.

With so much to contend with, those teams with a clearly defined number one driver - such as Red Bull - could also have an advantage.

Prost did not agree with those who argue that the measure of Vettel's true greatness will only be fully apparent when he has won titles with more than one outfit, as the three other four-time champions all did.

"For sure, if he moved to another team and wins with them, it would help. But I have to be realistic, if I was in his position, I would not move," said Prost, a champion with McLaren and Williams.
