The winger fired home the Foxes' debut goal in Europe in Wednesday night's 3-0 victory over Club Brugge and could not hide his contentment at contributing to the cause on such an important level.
"It's massive," Albrighton told LCFC TV.
"I'm not going to play it down because it's probably one of the biggest achievements of my career so far. It's massive for me and my family because it will live with me forever.
"I can always look back and say I've done that and hopefully with a few more games left in the competition, I can chip in with a few more.
"Just to be there is sensational and to score is just that one better. For everything that my family have done for me and supported me throughout, it's massive for me, but it's massive for them as well.
"It's something that I'm sure they're all proud."
