Staying cool is key to success, says Verstappen senior

Barcelona: Staying cool under pressure is the key to teenager Max Verstappen's success in becoming the youngest race winner in Formula One history.

That is the opinion of the man who knows him best, his father Jos, a former F1 driver who watched in awe on Sunday as his 18-year-old son, the first Dutchman to do so, claimed his record-breaking victory in the Spanish Grand Prix.

As all around him celebrated one of the most stunning achievements in motor sport, Verstappen senior reflected on how his son had resisted all attacks to win ahead of Ferrari's two world champion drivers, Finn Kimi Raikkonen and German Sebastian Vettel, on his debut with the Red Bull team.

"He's cool, he knows what to do, but this is his life," he said. "He has been racing his whole life, so it's quite normal for him, but to win a Formula One race will always be very special, particularly with the way he won it.

"He was always in control, he didn't make mistakes, and he deserved it."

A sensational opening-lap collision between the two Mercedes drivers, defending three-time champion Lewis Hamilton and championship leader Nico Rosberg, set the stage for Verstappen.

A strategy switch, taking him from three stops to two and doing the reverse for his more experienced Australian team-mate Daniel Ricciardo, was also instrumental.

But it was down to the driver to take his opportunity to win just 10 days after being promoted from the junior Toro Rosso team to replace Russian Daniil Kvyat.

"A lot has happened in the last two weeks, but the most important thing is Max can cope with it all," said Verstappen senior.

"He has put in a lot of hard work with excitement for himself to be driving a top car and for a top team. He's very flexible and he's shown that again."

Father Jos drove 106 races in his career, but was never a winner. His son has claimed a win in his 24th outing.

"To come into a new team and have an achievement like this, it's unbelievable," he said. "I never thought for a moment that after only just changing teams such a thing could happen, not in this way, but we knew we had more chances to win.

"Red Bull is a top team and they know how to win races."
