Asked if it was Bottas' most impressive showing of the year, Shovlin said: "Yeah, I think it was definitely.
"He was very impressive in qualifying. He had a tricky morning session but really got it together with a very, very solid qualifying.
"In the race, Valtteri has often found it harder than Lewis to get through the traffic but he overtook more than anyone. He just kept attacking and attacking, keeping the tyres in good shape so we're super proud of the job he has done."
At one stage, when Bottas was scything his way past his rivals on the medium tyre compared to many around him on the hard, it appeared as if he was on course for victory.
As to whether the win was genuinely on, Shovlin added: "Certainly he was thinking that way. He went into the day saying he was going to end up on the podium so we've seen a lot of fighting spirit from him.
"And there are windows on that medium that we would have had a bit better warm-up on the restart but unfortunately everyone seemed to be doing the same straight line [speed].
"The DRS also has a very, very small effect because the rear wing doesn't have anything like the normal level of drag. We're always optimistic but he did well to get the podium."
