Mark Webber has played down Red Bull's chances of getting pole position in Germany, saying Mercedes are the team to beat.
Lewis Hamilton and Nico Rosberg locked out the front row of the grid at Silverstone last week and the Mercedes duo followed it up with the top two places in Free Practice One at the Nurburgring on Friday morning.
Red Bull, who are favourites with Paddy Power to win this year's Constructors' Championship, hit back in the afternoon as Sebastian Vettel claimed P1 with a 1:30.416 on the soft tyres with Rosberg second fastest and Webber completing the top three.
Despite their impressive pace late in the day, Webber feels Mercedes are likely to dominate proceedings during qualifying at the Nurburgring.
"We are not putting our hopes up for tomorrow," said the Australian. "Obviously Mercedes is more than capable of doing a front row lockout which we have seen for the last few races.
"Seb and I look a bit more competitive on one lap today, but Mercedes could put the fuel in.
"We need to keep working hard and it is similar for the race: Mercedes has proved in the last few weeks that it is not slow on Sundays, so there are a few guys that are in contention for the win."
Mercedes' recent impressive form has seen them move to second in the standings and they are now also second favourites in both Championships. To bet on Merc and more visit Paddy Power.
