The 24-year-old, who joined from Vitesse in the close-season for a club-record fee of £12 million, made only his fifth Premier League start when Mark Hughes's men visited the Liberty Stadium.
Bony's double against Stoke doubled his league tally and Laudrup believes that his charge is showing constant improvement, of particular importance following talisman Michu's ankle injury.

"There's always something special when you have a certain price tag on your shoulder but he had a good performance [against Kuban Krasnodar], especially in the first hour. He scored a goal. The same [on Sunday], he scored two goals so I am pleased with that.
"Scoring goals is one thing but it's important. I can see him in training as well, he gets into better shape and he really wants to improve and then again the goals are important because especially if you play up front, you are always judged.
"As a striker with a big price tag, you are even more judged by the goals you score or don't score, so it's important and especially now that we don't have Michu. We don't have him, so others can score."
