The 26-year-old striker is currently on a three-month loan at Molineux from Hull City, but has made just three appearances since joining the Championship side.
Jackett has said that the Ivorian is short of sharpness and must quickly prove his worth to the team.
"We were hoping he'd make an immediate impact – he wasn't brought in with us thinking 'we need three months with this guy.' It was with the intention that he could come straightaway. But he needs games to get to his sharpest," Jackett told the Express & Star.
"He looks short of match practice and he's been a substitute with me playing mainly Dave Edwards and Nouha Dicko. Sagbo's job is to keep pushing them and when he gets that opportunity – and he's had some minutes – to keep one out of the team.
"When he gets a chance, he needs to state a case for more. It really depends on how well you show."
Sagbo came off the bench in Wolves's 3-3 draw with Millwall at The Den on Saturday.
