“It was a difficult one to take against Crystal Palace," said Ighalo.
“If we'd have won, we'd have played United in the final. Unfortunately, we lost.
“It was a bitter one to take but this is an opportunity again in an FA Cup semi-final to make it right and go forward to the final.
“To get to the final would be great for me in my life and my career.
Ighalo, speaking to United's official website, added: “Now I have the opportunity to get to the final with the club I've supported all my life.
“It would make my dreams perfect. It will be tough, but we have what it takes."
