The youngster joined Die Wolfe in 2016 but was allowed to sign a professional contract in January 2017 after he turned 18.
Osimhen's progress at the German Bundesliga side was halted by a knee injury that had him appear only twice for Andries Jonker's side last season.
"He made a perfect move. I know Wolfsburg as a team and also, as a player with Schalke," Agali told Goal .
"I've always been afraid playing against Wolfsburg because it has always been a tough match for me and I know their mentality.
"I hope they still have that mentality.
"If he's patient, he will serve this country. I've seen Osimhen play; he has the quality of a good striker; stay around the box, be patient, look for your chance and score.
"And being in Germany affords him the chance [to master his crafts]," he concluded.
