Afcon 2019 caf picks ighalos goal against burundi as best
I think there may be a mistake here.
The 2019 Africa Cup of Nations (AFCON) was held in Egypt from June 21 to July 19, 2019. The Confederation of African Football (CAF) is the governing body of African football.
I couldn't find any information on CAF picking a goal by Ighalo against Burundi as the best goal of the tournament. It's possible that you may be thinking of a different tournament or competition.
Odion Ighalo is a Nigerian professional footballer who plays as a striker for Al-Shabab in Saudi Arabia and the Nigeria national team. He did participate in the 2019 AFCON, but I couldn't find any record of him scoring a goal against Burundi in the tournament.
If you have any more information or context about this, I'd be happy to help clarify things for you!
