Mark Webber and Sebastian Vettel anticipate that Ferrari will be the main obstacle in the way of a victory in German Grand Prix this weekend.

Fernadno Alonso have set the best time in the second free practice session at Hockenheim, while his team-mate, Felipe Masa, finished third.

After these results, both Red Bull F1 Team drivers believe that Ferrari will manage to get a very good result and admit that Scuderia may mean some problems this weekend. Though, Sebastian Vettel admits that the rain that fell on the track makes the times difficult to translate.

Red Bull is currently second in F1 Constructors' Championship, with Ferrari following them 84 points behind

“Ferrari looks extremely competitive and I think McLaren probably had a difficult day today with only one car for the majority of the training so we will see tomorrow. The conditions were changing all the time, so to really judge the lap times is quite difficult because you have to see when everyone was out on the circuit and in which conditions. The car feels nice, especially in the last section, so all in all it is a good day. Ferrari looked very quick and McLaren had a difficult day in the office, with only one car for a majority of the running, but I am sure they will be back up there tomorrow. It is tight,” said the German.

At his turn, Mark Webber highlighted the thread Ferrari represents after the good times they recorded Friday afternoon.

“The car felt pretty good. We have some work to do tonight. Ferrari look strong, so we have some competition this weekend and are looking forward to the race,” said the Australian.

Ferrari and Red Bull Racing have split the first four positions in the second free practice session, while Lewis Hamilton lost three quarters of the time in the garage due a crash he suffered in the morning, when he damaged the rear of his McLaren F1 car, including the new diffuser.
