The 24-year-old Ivory Coast international has scored four goals in the English top flight and five in the Europa League this season, having joined the Swans from Vitesse in the summer.
"I am just adjusting to the best league in the word," he told Sky Sports News. "The challenge is to convince people because of the money the club paid for me - it has not been easy but I am getting there.
"The manager (Michael Laudrup) trusts me and has a plan to use me to help me find my feet in the league. Scoring twice in the league against Stoke City on Saturday was very good.
"I want to score every week for the club but I know that is difficult to do but I will try. I believe in myself and hope to make my name in the league."
Swansea are currently 13th in the league table with 12 points from 11 matches.
