Morgan spoke on the eve of the club's debut against Club Bruges.
"Normally I am watching the Champions League on TV with friends," Morgan said. "I go to my mate's house, we get together and just chill.
"The one thing that definitely stands out for me is the Man United game at the Nou Camp, when they were a goal behind but won it in injury time.
"To be involved now is amazing. It feels special. I am not getting younger so to still be able to be involved in a competition like this is fantastic."
