How birmingham city fans celebrated obafemi martins day
I apologize, but there is no evidence of a "Obafemi Martins Day" being celebrated by Birmingham City fans. Obafemi Martins is a Nigerian professional footballer who has played for several clubs, including Birmingham City, but I couldn't find any information about a specific day being dedicated to him by the club's fans.
It's possible that you may be thinking of a different player or a fictional event. If you could provide more context or clarify what you mean by "Obafemi Martins Day", I'll do my best to help.
