West Ham boss David Moyes was happy to beat Celtic with his father in the stands.
The Hammers were impressive for the 6-2 triumph.
Moyes told the club's website: "I was especially happy that my dad could come to see us play today, and I've learned so much from him and Celtic to take into my career…
"It's been hard for him to get down to West Ham games. He'll be at all the games hopefully next season if the rules permit, so it was good that he could come to see us win and we'll have a few beers together after the game before I head back to London over the weekend.
"He was the coach of an amateur team and as a boy I used to watch how they organised and the planning and I've been brought up in a real football family.
"He was very much about the young players, and I found when I played for Celtic they were very much about young players too, always promoting their young players and trying to get them in the team.
"I learned some really good habits and the big thing I learned at Celtic is that they want to play entertaining football and I thought in the first half they played very well today and gave us a really difficult game."
