Ighalo also revealed a surreal moment after playing for Watford at Old Trafford in March, 2016, his second visit to the Theatre of Dreams.
“When did I first set my eyes on it?” he said.
“It was in 2013 when I came to see the stadium, to visit it and go around, taking pictures outside the stadium. The first time I played there was for Watford in 2016.
”Manchester United is a big club. When I saw that, I was amazed. I was outside the stadium and I took pictures. Then I played there with Watford, against United, and it made me even more happy. I came out of the stadium and stood looking at it.
