Sebastian Vettel not concerned by win drought

The German won five of the opening six races this year, but has seen Fernando Alonso, Lewis Hamilton and Jenson Button win the last three events.

That form has already led to predictions that Vettel's dominance of F1 is over for now, but the man himself insists he is relaxed about the situation.

When asked by reporters if he was worried that he had not won since Valencia, Vettel said: "Not at all. It always depends on how you want to turn things. Obviously you are the ones who are starting to get worried. We had races where we were struggling a bit, but it worked out okay. I don't think it is a drama, which is why I am not really worried."

Vettel believes that Red Bull Racing has learned the lessons from the last few races - and is upbeat that the outfit still has good enough speed even though its car may not be ideal for the high-speed Spa layout.

"We need to see this weekend where we are," he said. "The weather can be tricky, so we will see. I am quite confident. I think we have learned from previous races, and we think we have understood a lot. We will see this weekend how much."

When asked if McLaren's back-to-back victories owed much to the recent cooler conditions, Vettel said: "No, they won because they finished ahead of the others and did a better job than the rest.

"Maybe we have not been at the very top of our game. We have struggled a little bit here and there, and they did a very good job, had straightforward races and won both of them.

"We have to accept that. I don't like it, we have to turn it around, but we respect the other teams as well. I respect the other drivers, and there are some very good drivers and teams in F1, so I don't think anybody is unbeatable."
