British GP: Ferrari F1 chief Arrivabene says glass 'half empty'

Vettel capitalised on changeable conditions to leap from fifth to third, jumping both Williams drivers by stopping at the right time to switch from slicks to intermediates.

But Ferrari chief Arrivabene said his team's first podium since the Monaco GP at the end of May was not a cause for celebration.

"The glass is half empty, not half full," Arrivabene said on Sunday night.

"We were doing a very good job in terms strategy - the rain helped us.

"But if the race was dry instead of wet the result was completely different.

"So if we want to be serious we need to start from there and to work on the problems that we have."

When asked what those problems were, he added: "We have to discuss it in-house.

"We were quite slow on the straights without gaining anything in the high-speed curves."

Kimi Raikkonen, whose gamble on making an early switch to intermediates did not pay off, dropping him to eighth, agreed that Ferrari struggled for top speed.

"We were faster than [Nico] Hulkenberg in the first stint but I couldn't get past," said the Finn.

"We weren't fast enough on the straights, where you really have the chance to overtake.

"The car was fine. It felt better than yesterday, all was OK, just the laptime was missing.

"I don't know for what reason, but the handling was as good as it could have been.

"Then the rain came and we chose to do something but it was too early.

"I thought it would keep raining, but it was four laps too early.

"It was the wrong choice, but it's what we tried."
