I dont care what anyone says ighalo confident after man utd double in fa cup win

I think there may be some confusion here!

Odion Ighalo did not play for Manchester United in the FA Cup, nor did he score a double in an FA Cup win. In fact, Ighalo is a Nigerian professional footballer who has played for several clubs, including Watford, Manchester United, and Shanghai Shenhua, among others.

It's possible that you may be thinking of a different player or match. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you out!
