Bottas wary of Red Bull threat in Bahrain

Mercedes were the dominant team during the first and second free practice for the Bahrain Grand Prix , but they are wary of what is behind them. Valtteri Bottas thinks Red Bull Racing could be a threat this weekend.

Good race pace Red Bull

"Red Bull will definitely be at the front, especially during the second practice session they looked very strong. But it's hard to say, because today we rode on different tires, which we had to test for Pirelli," said Bottas.

Bottas himself is happy with his day. "Based on the feeling in the car and the performance, it was a reasonable day. The first training session was a challenge. In the third free practice it will also be difficult because of the warm temperature, but overall we are in good shape," " added  Bottas.
