- Rivals know team to beat is Red Bull
- Others believe that they can mount a challenge
Jenson Button sounds less than confident about challenging Red Bull for pole in China.
I'd be surprised if we can fight them for pole.
Before back-to-back polesitter and winner Sebastian Vettel again went fastest in the last practice session before qualifying, Button was asked if McLaren has drawn level with Red Bull after a closer race in Malaysia a week ago.
"No, not at all at the moment," the Briton said in Shanghai. "I'd be surprised if we can fight them for pole. They're so fast."
When asked if 2011 is a reminder of Michael Schumacher's dominance at Ferrari some years ago, the Brazilian nodded.
"Yes, but I didn't have the pleasure of driving that Ferrari," Massa smiled.
Spain's AS newspaper said the RB7 is 20kph quicker through a quick corner in Shanghai than any other rival.
"I expect they will stay ahead for the whole year, it just remains to be seen whether the gap to the other teams stays the same through developments," wrote Jos Verstappen in his latest column for De Telegraaf.
But Mercedes' Norbert Haug is confident that Red Bull's current dominance will end.
"We know they are very fast," he told Kleine Zeitung, "but we have seen dominance before and, like before, Red Bull's will not be for ever."
