Cape Town - Kelechi Iheanacho's participation at the Olympic Games is in doubt as Manchester City have yet to give him the green light to represent Nigeria.
According to Nigeria Olympic team coach Samson Siasia, the Premier League club are yet to respond to several requests for Iheanacho to be released for the Rio spectacle, which starts in August.
"The Nigeria Football Federation has written several letters to them (Manchester City) wanting to know when the player would be released for the Games in Brazil, but as I speak with you the club has not replied," Siasia told the Manchester Evening News.
"So for now I cannot confidently tell you that Iheanacho would be available for the Olympics, although we are not relenting on the issue as the NFF is fighting tooth and nail to ensure we have our best players for the Olympics.
"Kelechi told me he is anxious to play in the Olympics and I am sure with much pressure the boy would be released eventually."
