The winger scored the only goal of the game during Saturday's trip to Blackburn Rovers as Wolves ran out 1-0 winners at Ewood Park.
Having been relegated from the top flight last season, summer signing Sako is hoping that Wolves can make a return at the first time of asking.
"I'm not thinking about the Premier League at the moment," Sako told the Express & Star. "I'm playing for Wolves and I'm enjoying it here.
"I hope to get to the Premier League with Wolves. We're all working hard to get the club back into the Premier League so promotion is what we're all hoping for.
"We're working very hard towards that aim so that we can be back there next season."
The 24-year-old has scored three Championship goals for Wolves.
