Nigeria coach Samson Siasia has issued an apology to Nigerians after the Super Eagles drew 2-2 against Guinea to miss out on the 2012 African Nations Cup. “This is a doom day. We have disappointed Nigerians. It is a very sad day for me in particular. I take responsibility. It is sad, very sad. We lost many chances. You don’t create such chances and miss them. If you do the story may not be good. That’s what happened. We are sorry”.
