Mercedes boss Toto Wolff hailed Valtteri Bottas' "amazing" win at the Russian Grand Prix but lamented the lack of pace on Lewis Hamilton's car.
Bottas claimed the first victory of his Formula 1 career after an absorbing battle with Sebastian Vettel at the death, while Hamilton was cut well adrift of the final podium spot in P4 and finished 36 seconds behind his team-mate.
"An amazing first win for Valtteri and a fantastic race," Wolff told BBC Sport.
"The bittersweet part is we did not have the pace on Lewis' car. We hoped strategy-wise there would be a safety car for him, but there wasn't one."
Wolff then gave an insight into Bottas' character and elaborated on the problems that Hamilton faced in race.
"Valtteri is just a very cool guy," he added to Sky Sports F1. "There was lots of a pressure on him with a four-time World Champion behind him and bar one mistake he was very calm in the final laps.
"I think the 30 second gap to Lewis does not reflect the right picture. There was no more to gain for him at the end.
"Kimi's pace was lightning quick and once you are struggling with the balance of the car then you are lacking pace and that's what happened today with Lewis."
