The call comes after the Nigerian forward endured a disappointing night during Tuesday’s UEFA Champions League encounter with Barcelona.
Barcelona secured a 4-1 victory at Rams Park, extending their winning streak to ten matches.
Barcelona’s aggressive defensive setup proved effective in limiting Osimhen’s influence, as the forward recorded just 12 touches, attempted three passes and completed two.
The Nigerian also won three of nine contested challenges, lost possession six times and managed just one shot, which went wide.
Galatasaray were caught offside eight times during the match, with Osimhen responsible for six of the offences.
“Among Galatasaray’s eight offside infractions, Osimhen committed six. Okan Buruk must unquestionably address Osimhen’s offside issue,” Özkök said during an appearance on A Spor.
The Barcelona match was the first time this season that Osimhen neither scored nor provided an assist in a competitive game.
